• Intel D2500HN Atom D2500 Doesn't turn on

  - by David W

  I recently bought parts from Amazon to build an embedded PC, and have assembled everything. I have: Intel D2500HN Mini-ITX Motherboard Mini-Box Pico-PSU 80 M350 Universal Min-ITX Enclosure 2GB DDR3 Memory Kinamax AD-LCD12 LCD Monitors 12V 6A 72W AC Adapter Power Supply The motherboard gets a light (on the motherboard, not on the Pico-PSU) when I plug it into the power adapter. Furthermore, I see the power switch light come on when I press the power button. However, the display doesn't turn on, and it doesn't seem that the PC is actually turned on. Since I'm seeing these lights, I know that the motherboard is getting power. Furthermore, the display VGA port is embedded into the motherboard, so that's not the issue. I'm just trying to figure out what COULD be the issue aside from a faulty motherboard. I have a diagram of the D2500HN motherboard which labels everything, and have ensured that the power LED as well as the On/Off cables are plugged into the right spots, although to be sure I've tried flipping these two cables around, and also plugging 1 cable into the other cable's spot & vice-versa. Is there anything else you folks think I may be missing, or anything else I can do to try to troubleshoot this issue before sending the motherboard back?

• (Mac Intel) HP PS driver prints in B&W from Adobe Reader after installing Cannon PS driver

  - by JohnB

  I have a unique problem that leaves me at a loss as to where to start troubleshooting. We have three Macs we use for graphics, two of which are PowerPC and one which is Intel. They are set up to print to an HP 5500dn, but occasionally this printer gets tied up with a massive print job, so I installed the PS driver (iR-PSv1.81MacOSX) for the Cannon C3200 Printer/copier on each of the machines. Both of the PowerPC Macs installed without issue, but the Intel Mac exhibits strange behavior: I've confirmed that while the Cannon driver is installed (whether or not the Cannon is set up for printing in print settings), the HP 5500dn will print in color from Safari, but only prints in black and white from Adobe Reader. The Cannon printer itself has not exhibited any strange behavior As soon as the Cannon driver is uninstalled, the HP 5500dn prints in color from Adobe Reader again. We run a network of Windows PCs, and the 'Mac room' mostly takes care of itself, so we don't have any experienced Mac administrators onsite. The Cannon is capable of Appletalk, but the PS driver seemed easier to work with (and Appletalk is currently disable on the Cannon. I'm not against using the Appletalk compatible drivers, but I would rather use the PS driver if at all possible - I don't want to open up the proverbial can of worms. If someone has any clues or suggestions that would help troubleshoot this problem, I would be grateful. I've already done some googling, but due to the obscure nature of this problem, I haven't been very successful. I don't like to create multiple threads on multiple sites, but I'm posting here due to Chopper3's suggestion on my post on ServerFault (http://serverfault.com/questions/135349/mac-intel-hp-ps-driver-prints-in-bw-from-adobe-reader-after-installing-cannon)

• How to monitor changes in the frequency of network latency spikes over time?

  - by dequis

  I'm currently trying to troubleshoot an issue with my network in which I get latency spikes up to 200 seconds (normally around 50 secs) in an apparently random way at apparently random moments of the day. While trying to find what part of my messy network needs to be blamed (outside of the scope of this question - discussed a bit on chat), I realized I have no reliable way to confirm that a change actually improved anything. So far, the main way in which i notice this is that irssi shows [Lag: 15 (??)] in the statusbar, increasing every 5 seconds, and all other connections seem to be affected too. Since this depends on my observations, it's not a very reliable method to know how often it really happens. Note that just sending ICMP pings is probably not enough, but that's just my guess. It might be a "bufferbloat" issue, it might be packet loss, it might only apply to persistent connections. I suspect this because a few months ago, when the issue started, I had a "ping" command running in background and it didn't show anything weird at all during the latency spikes. This seems to have changed now (pings don't go through), but still, I'd prefer something more robust.

• Basic Apache setup is not seeing my site

  - by Jakobud

  Sorry that is a horrible thread subject, but I cannot think of a better more descriptive subject. We are running a Fedora 11 server that is currently hosting some CRM on it. I want to use a VirtualHost directive to add another site to the server. So I created this conf: /etc/httpd/conf.d/mysite.ourdomain.com.conf And here is the content: <VirtualHost *:80> ServerName mysite.ourdomain.com DocumentRoot /www/mysite ServerAdmin [email protected] ErrorLog /var/log/mysite.ourdomain.com-error.log CustomLog /var/log/mysite.ourdomain.com-access.log common </VirtualHost> I restarted apache, getting the following warning: [warn] NameVirtualHost *:80 has no VirtualHosts From what I read, this warning is not related and I can ignore it and my site should still be up and running, correct? (I'll troubleshoot this error later if so) Well I have our DNS server setup to point mysite.ourdomain.com to goto this server. I can ping it and it points to the correct LAN IP, etc.. Now when I try to access it in the browswer I get nothing. It just says Connecting... and never gets there. If I try mysite.ourdomain.com or the IP address, neither one doesn't get there. It's a very simple and basic apache setup so I'm not sure what I'm doing wrong... Like I said, the other thing that is running on this server is a crm and it's .conf looks something like this: Listen x.x.x.x:443 <VirtualHost x.x.x.x:443> ServerAdmin [email protected] ServerName crm.ourdomain.com ErrorLog /var/log/httpd/ourdomain/crm-error.log CustomLog /var/log/httpd/ourdomain/crm-access.log common DocumentRoot /www/ourdomain/crm <IfModule mod_dir.c> DirectoryIndex /index.php </IfModule> </VirtualHost> There is also some LDAP authentication stuff in that config but I left it out cause I assumed it wasn't necessary to post. Anyone have any clue where I should start or what settings I can post from httpd.conf that would help?

• SSL stops working on IIS7 after a reboot

  - by Mark Seemann

  I have a Windows 2008 Server with IIS7. Every time the server reboots, SSL stops working. Normal HTTP requests work fine, but any request to an HTTPS address gives the typical error message in the browser: Cannot find server or DNS I can temporarily fix it by opening IIS Manager and bring up the Bindings… window for the website in question. Then I select “https”, click on “Edit” then click “Ok” without making any changes to the settings. After doing this, browsing to https:// works again until the next reboot. This issue look as lot like the one described here, but according to the Certificates MMC snapin, the certificate in question does have a private key. I'm also pretty sure that I never installed the certificate in the personal store, but imported it straight into the machine store, but it's been a while... There's not a lot in the event log apart from the event ID 36870 also described in the post I linked to. Can anyone help me troubleshoot this issue so that SSL will work even after a server reboot?

• Cannot 301 redirect with IIS URL Rewrite Module

  - by Justin

  I am trying to troubleshoot my issue with the URL Rewrite Module on IIS 7. I migrated a Wordpress blog over to BlogEngine.net. There were only about 5 entries that I wanted to use 301 redirects to the new blog, so I wanted to simply create 5 exact match redirect rules using the rewrite module. For some reason the exact match rule never seems to take effect, I always get a 404 error when the original url is navigated to. I verified that my exact match pattern matched the existing backlinks and it does. I then tried a simple test and got the same behavior, no redirection. I created a page, test.html, on my site, I then created a second page, test2.html. So my exact match pattern is: "http://www.mydomain.com/test.html" And the rule is supposed to do a 301 redirect to "http://www.mydomain.com/test2.html " The redirect never happens. I created the steps for the rule based on the instructions in this page: http://learn.iis.net/page.aspx/461/creating-rewrite-rules-for-the-url-rewrite-module/ I don't see that I left out a step. After I apply the rule I've even gone as far as doing an IISReset to make sure it would be in effect but still no luck. Any thoughts on what I might have left out? (Note: my rewrite rules dont include the " " around them but I had to add since serverfault thinks I am trying to spam the system with multiple urls.)

• Some URLs fail to load on Windows web portal

  - by jpolache

  I’m working in a large data center and have been assigned to troubleshoot and issue with a windows (IIS) web server that acts as a portal for a customer of the data center. This portal server is on a DMZ at the local data center. I don’t have access to the portal desktop and am relying on an off-site administrator to work with me to do testing and report the condition of the portal. He tells me there are no software firewalls or other filtering configured. While most of the remote web pages work fine, several of the URSs the portal is suppose to serve up fail to load. I had wireshark installed on the portal system and had a capture taken of one of the failures. I used IE to access one of the remote web servers at issue. I could see the TCP SYN-ACK coming back from the remote server, but after several HTTP GETs fail to get a response the portal server sends a reset. The webmaster of the remote web server assures me that no sites are being blocked. I had a capture taken outside the local firewall, so there should be no issue there. Another tech set up a laptop and used the IP address of the portal (we took the portal off-line for the test). The laptop loads the URL as expected. I tried having Firefox loaded to make sure that the HTTP GET was not mal-formed. Same failure as with IE. So, it seems it is not the remote web server or the network, because there was no problem with the laptop. At this point, I’m not sure what other questions to ask or tests to do.

• Vista WHS Client stopped resolving local names

  - by andrewcr

  I’m running Windows Home Server PP2 in my home, with 3 client computers: two XP and one Vista. I have a router that provides my local DHCP and the server has a static IP address. The other day the Vista machine hung, and on reboot stopped resolving local names. It will show the green home server client icon in the system tray, but if I attempt to log in to the console, I get a “This computer cannot connect to your home server” message. If I ping the server name from the command line, it does not resolve, and gives a “could not find host” message. Oddly enough, if I browse the network, I can see the server, but double clicking on it fails. The other machines on the local network have no problems seeing the server, and the Vista machine has no problems resolving names from the internet, it just can’t see any local machines. I’m aware that I can work around this by adding entries to my HOSTS file (it does work), but I’d like this to work the way it’s “supposed” to. I’m an experienced computer user and developer, but not a networking whiz. Can anyone tell me how local name resolution is supposed to work in my environment and/or suggest ways to troubleshoot this? Thanks, Andy

• Should windows services be created with custom users, or should I use one of LocalSystem/LocalServic

  - by Justin Dearing

  I'm asking the question in general for the average custom developed NT service or unix OSS daemon ported to windows with SCM support. However, at the moment my immediate concern is for mongodb. From my experience with UNIX I like all my services to run as different unprivileged users. The way this has translated to windows is as follows: Create a local (or domain if it has to talk to SQL server) windows user with a long random password (lately an ASCII85 encoded guid generated from a different machine). Set it to next expire and forbid it from changing its password. Remove that user from the "Users Group". Grant that user "Login as a Service" permission. Give it read permission to the folder where the app resides, and write permission to the logs and data files the applications use. Assign the user to the service. Troubleshoot until the service starts. My feeling is that the unprivileged users are less powerful than the 3 special service users. I also feel that by isolating which users run which services, I would limit collateral damage if a way to compromise one service was found.

• What Wireless Router/ADSL Modem to get? N-band a must!!

  - by JJarava

  I'm looking for a Dual-N band Router OR ADSL Gateway and I'd like some recommendations. Situation: I have a 802.11b/g ADSL gateway provided by my telco, but the WIFI signal won't cover all the house (especially the living-room, so my tv-connected Mac Mini has poor to no internet access). So I'm looking to either replace the DSL modem with a N-enabled one, or to add a Router to the mix. I've had a modem+router setup for many years, and I know the advantatges (double NAT, double FW = more security) and issues (more complex to troubleshoot, two possible points of failure), so I'd rather live with a single (ADSL Gateway) device, if possible. Requirements: Dual-N Band (300 Mbs WIFI) 1 GB Ethernet ports ADSL2+ support (if it's a ADSL gateway, which would be desirable) "Best" range and speed possible Nice to have: USB port to share disks/printers on the network Media streaming I've been a long time user of Linksys, so googling around I found the WRT610N (http://www.linksysbycisco.com/US/en/products/WRT610N) for a "Pure Router" perspective, and it's one of those that Linksys styles "N++" (http://www.linksysbycisco.com/US/en/promo/Promotion-Go-Wireless?stepname=Promotion-Step-Go-Wireless-High-Performance) But I haven't been able to find similar "ADSL" gateways. I've found the WAG320N, but there is little to no info in the Linksys site (i.e., i don't know if it's Dual Band, or if it has GB ethernet) Any opinions/recommendations of other products/suggestions are more than welcome.

• Network Load Balancing, intermittent port problem

  - by Jimmy Chandra

  Trying to troubleshoot an intermittent problem. I think it might be related to an NLB issue. We are using Windows Network Load Balancing to balance load for our multiserver SharePoint front ends. Say... Web Front End 1 IP is 192.168.1.100 and Web Front End 2 IP is 192.168.1.101, the NLB is setup to load balance both WFE servers on any incoming traffic to the IP 192.168.1.200. Sometimes we got an intermittent issue where when we try to access the SharePoint site using 192.168.1.200:8080 (say the site is set up to run on port 8080) from a remote client, it will display page not found. Pinging the 192.168.1.200 will give responses, but when trying to telnet to 192.168.1.200:8080 it just won't connect. However, browsing the SharePoint site directly on individual WFE (192.168.1.100 and 192.168.1.101) show no problem whatsoever. My guess also (we didn't get a chance to try it yet, but I think it should work), if I try connecting remotely to individual server, it will respond just fine. But any attempt on trying to connect using the virtual IP (192.168.1.200) will fail miserably. Funny thing is, after a while it will return back to normal. Anyone had similar experience with this type of problem while implementing NLB before? We are doing this in a virtual environment.

• Is there any special way to force GoBack to work with Windows Vista and 7?

  - by dfree

  Norton/Roxio's GoBack doesn't work with Vista/7 for reasons unknown. I have tried several alternatives (Norton Ghost, RollbackRX, Norton Save and Restore), none of which offer the same functionality as GoBack. Not only does GoBack not eat up all your hard drive space while creating a legitimate fail safe for any pc problems, it also allows you to see ACTIVELY EXACTLY WHAT PROCESS ARE BEING EXECUTED ON YOUR COMPUTER. This feature (called Advanced Disk Drive Restore) also allows you to troubleshoot problems and determine causes for things in about half a second by seeing what is happening on your machine. It's how I learned everything I know about computers. GoBack also features something called Safe Try Mode where you can put it in SafeTry and then mess up the whole computer and when you come out of it, your computer will be exactly how it was before. Amazing for people who like to tinker without risking their machine stability. It also helps for that accidentally erased paper or whatever you may have erased. I believe GoBack installs a type44 partition around the drive, which loads prior to windows to allow this functionality. If you're going to recommend another program, please don't (unless it does all of the above). I've tried all the competition and nothing is as good. I just want my GoBack to work with 7 :) Any ideas of crazy ways to make this work?

• postfix says mail sent ok, message does not arrive in ISPs inbox? no reject in log?

  - by Nick

  When I send a test message from my mail server to my @bellsouth.net email, The postfix log shows it was sent OK, but the message never arrives in my bellsouth inbox. Shouldn't I get a failure notice or a bounce if At&T is blocking the messages? I'm trying to troubleshoot why some customers aren't getting emails, but if there's nothing in mail.log to say the message is rejected, how do I know which messages were delivered successfully? The log shows: Feb 27 09:02:36 MyHOSTNAME postfix/pickup[26175]: D53A72713E5: uid=0 from=<root> Feb 27 09:02:36 MyHOSTNAME postfix/cleanup[26487]: D53A72713E5: message-id=<[email protected]> Feb 27 09:02:36 MyHOSTNAME postfix/qmgr[5595]: D53A72713E5: from=<[email protected]>, size=878, nrcpt=1 (queue active) Feb 27 09:02:37 MyHOSTNAME postfix/smtp[26490]: D53A72713E5: to=<[email protected]>, relay=gateway-f1.isp.att.net[204.127.217.16]:25, delay=0.57, delays=0.11/0.03/0.23/0.19, dsn=2.0.0, status=sent (250 ok ; id=20120227140036M0700qer4ne) Feb 27 09:02:37 MyHOSTNAME postfix/qmgr[5595]: D53A72713E5: removed The AT&T server accepted the message, right? I happen to have an At&T/Bellsouth email, but I don't have an account with every ISP we send to. I need some way of knowing if a message is getting to its destination or not. Is there any setting in my main.cf file that would affect whether or not we get reject/bounce notices?

• Trouble with IIS SMTP relaying to Gmail

  - by saille

  I appreciate that similar questions have been asked about how to setup SMTP relaying with IIS's virtual SMTP server. However I'm still completely stumped on this problem. Here's the setup: IIS 6.0 SMTP server running on Win2k3 box with a NAT'ed IP. Company uses Gmail for all email services. An app on the box needs to send email, so normally we'd just set the app up to talk to smtp.gmail.com directly, but this app doesn't support TLS. Easy, we just setup a local SMTP relay right? So I thought. What we have done so far: Setup IIS SMTP server to relay to smtp.gmail.com, as per these excellent instructions: http://fmuntean.wordpress.com/2008/10/26/how-to-configure-iis-smtp-server-to-forward-emails-using-a-gmail-account/ The local SMTP relay allows anonymous access. Both the local IP and the loopback IP have been explicitly allowed in the Connection and Relay dialogs. Tried sending email from 2 different apps via the local SMTP server, but failed (the emails end up in the Queue folder, but never get sent). The IIS logs show the conversation with the local app, but zero conversation happening with smtp.gmail.com. The port used by gmail is open outbound, and indeed the apps we have that support TLS can send email directly via smtp.gmail.com, so there is no problem with the network. At this point I changed the smtp settings in IIS SMTP server to use a different external SMTP server and hey-presto, the local apps can send email via local IIS SMTP relay. So smtp.gmail.com fails to work with our IIS SMTP relay, but another 3rd party SMTP service works fine. We need to use smtp.gmail.com, so how to troubleshoot this one?

• Slow network file transfer (under 20KB/s) on newly built x64 Win7

  - by Mangoshake

  I am getting <20KB/s for local network file transfer. If I transfer a very small file (less than 100KB) it would start quickly then slow down to <20KB/s. all subsequently network file transfer would be slow, a reboot is needed to reset this. If I transfer a large file it would be stuck on calculating for a long time and then begin with <20KB/s immediately. This is a newly built desktop running Windows 7 x64 SP1. Realtek gigabit LAN from the motherboard (ASRock Extreme3 gen3). Problematic speed is observed on the private LAN, both through ethernet and WiFi. The Router is D-Link DIR-655. Remote Differential Compression is off. Drivers are up-to-date from ASRock's website. I have tested network file transfer to and from another Windows 7 laptop and a MacBook Pro, so I am fairly certain it is the desktop's problem. The slow speed only happens with one direction also, outbound from the desktop, regardless of whether I initiate the file transfer action from the origin or the destination. Inbound network file transfer and internet speeds are fine, so I don't think this is a hardware issue. I am getting 74.8MB/s internet upload speed from speedtest.net (http://www.speedtest.net/result/1852752479.png). Inbound network file transfer I can get around 10-15MB/s. I am hoping this community has some insight for me to troubleshoot this. I don't see anything obviously related from the Event Viewer, and beyond that I just don't know where else to look. Any suggestions are greatly appreciated, thank you in advance.

• Pure Terminal Server 2003 system hangs

  - by Donovan

  System Profile: IBM Server hardware Windows Ent Server 2003 running terminal services. No Citrix. Max user load: 30 Symptoms: While in the course of normal operation our terminal server will hang up. As far as I can tell there isn't any trigger that's plainly visible yet. The way in witch it hangs may give a clue though. The hang presents its self by users not being able to initiate any new processes. All processes currently loaded into memory work just fine. Example: outlook 2007. You may continue to read email, operate the client and such. Some people don't even realize the hang has occurred for a bit of time. My attempts to troubleshoot have been futile. Reacting to the hang does no good because I can't start any new processes to investigate. After I reboot the server my next instinct would be to begin logging to catch the hang occurring but I'm not sure what to log. Right now I'm attempting to keep process explorer running in case the issue occurs again. Sometimes it happens twice a day, other times, once a week. Anyone have any ideas on how I could set myself up for better success in tracking this problem down? Thanks, Donovan

• NVidia Graphic Card troubleshooting

  - by Berry Langerak

  My dad has a HP pavilion laptop, which is over 6 years old. It contains an onboard graphic card, a NVidia GeForce 8400M GS. Since a week or two, he's getting BSOD in Windows Vista. Also, the screen was acting up; strange lines and figures keep creeping up, but only once in a while -- not always. Thinking that it might be the drivers he had recently upgraded, I decided to downgrade the driver, with no luck at all. I then continued to deinstall the driver, and reinstalling the current stable version, but alas, to no prevail. Windows kept crashing during the course of the last two weeks, and thinking it might be Windows breaking up, I decided to upgrade his Vista installation to Windows 7, as I've been hearing good things about it. Alas, even that didn't help, and it seems the strange lines and figures keep popping up. I've opened the laptop itself, thinking it might simply be overheating because of clogging in the vents, but that's not the case, it's clean as a whistle. Now for the actual question; does anyone have a decent flowchart on how to troubleshoot such issues? It might well be the videocard itself, as the strange lines and figures sometimes even appear during BIOS and POST, but I'm not sure.

• Command prompt hangs/freezes/crashes sporadically

  - by Leonard Challis

  I'm finding it very difficult to Google this, I don't seem to be able to find anyone with the same issue and I don't know enough about the Windows operating system to troubleshoot. The machine(s) we are seeing the problem on are Windows 7 (professional) both 64bit and 32bit. The problem is with the command prompt freezing up, seemingly randomly. When it does freeze nothing will bring it back to life (i.e. keypress) and it's nothing to do with Quick Insert mode either. It doesn't seem to be when I run standard commands, such as cd, dir, etc, but when I run different programs from the command line. The annoying thing is that sometimes the prompt will freeze and at other times it won't, using the same program/command in the prompt. To add to the frustration, one of my colleagues who had the same problem seems to not have experienced it for a few days now (we're pretty heavy on the command line). It's not a VPN/RDP thing as suggested in other questions and forum posts, as I've seen this both locally and remotely. I thought it was to do with the return code signifying an error or some error state in the program, i.e.: C:\Users\leonardc>mysql -u lalala ERROR 1045 (28000): Access denied for user 'lalala'@'localhost' (using password: NO) but this isn't always the case either. In fact the above command hasn't crashed the shell before. Elevating the prompt to run as Administrator doesn't seem to have any bearing on the problem either. Disabling my anti-virus doesn't have an effect either. Update: I tried the same commands in PowerShell, but I still get the same problem, it will freeze at random times (more often than not, as with the command prompt, but not always). It's not the same as command prompt in the fact that one might work while the other doesn't, but then the next time I try run the same command in both it will suddenly be different again.

• TV won't go into standby

  - by Robert

  When I select Start-Turn off computer-Standby the 'turn off computer' option window closes, and then nothing else happens. I can start new applications, and Windows acts like I never selected standby. I ran it for several hours after that. If I have a TV program scheduled to record when I select standby I get a window (the Pinnacle TV software) asking if I'm sure, there are programs scheduled to record - and the computer just keeps running after I select yes, never going into standby. I added that detail as it shows the standby process is starting. [This problem also happens if a TV program is not scheduled, so the scheduler task in not running/in memory. This problem happens regardless of whether I'm not watching TV. This problem happens regardless of whether Media Center is running (it usually isn't, I'm using Pinnacle to watch TV).] I looked at "How to troubleshoot hibernation and standby issues in Windows XP" http://support.microsoft.com/kb/907477 - ACPI is enabled, and "standby" is an option in "Power Options Properties." So it appears to be setup correctly. Windows XP SP3 Media Center Edition, all current updates installed.

• Dynamic ARP Entries turning into Static ARP entries

  - by Zach

  I recently acquired a client that has a strange ARP caching issue on one of thier servers. I have a server that will eventually start turning it's dynamic ARP entries into static ARP entries. This causes problems because when the machine that has a static ARP entries on this server receives a new IP via DHCP, then the server is not able to communicate with the clients. Clearing the ARP cache resolves the issue and the server is fine for about a week and then it starts slowly turning ARP entries into static ARP entries. I haven't narrowed it down to when or how many it starts to do, but slowly you start seeing 1 static ARP and then 5 and then 10. The server in question is a Windows Server 2003 SP2. It is a DC, DHCP, and DNS server. I've checked the DHCP scope options and there's nothing in there that would indicate anything to do with static ARP entries. The only thing different between this DNS server and our other DNS server is that the 'Dynamically Update DNA A and PTR records for DHCP clients that do not request updates' is checked on the problematic server. I've done a bit of research about this and it seems that this may happen if any PXE type services are running, from what I can tell, there is nothing running a PXE server. I'm a bit lost as I have never seen dynamic ARP entries start to turn into static ARP entries. Right now my solution is a schedule task that runs every 24 hours to clear the ARP cache (arp -d *). I would like to not rely on this schedule task. Has anybody seen this before or have any suggestions on how to troubleshoot this?

• Understanding Exchange User Monitor (ExMon) Output

  - by SturdyErde

  I recently downloaded and ran ExMon while trying to troubleshoot Outlook connectivity problems due to high CPU usage on Exchange Server 2010 SP2 UR8. The tool provides a great set of data, but I have not yet figured out how to make great use of it. My first question is why the Exchange Server itself shows up as a high-use MAPI client in the ExMon data. Among the users' client versions I see build numbers listed for Outlook 2013, 2010, and yes, even 2007 clients. I also see build number 14.2.387.0, which represents Exchange Server 2010 SP2 Update Rollup 8 (+/- some other patch that makes it not quite match the UR8 number). There are many user rows that list only "::1" and/or the short hostname of my Exchange server in the 'Client IP Addresses' column. Some other columns include the end-user's actual IP address and the Exchange server's IP address. ExMon shows that it is actually Exchange Server that is utilizing the highest percentage of CPU that is used for MAPI calls. I had expected to see 1 IP address and version number for each user reported by ExMon. Instead, most records show multiple version #'s (Exchange ver and Outlook ver) and multiple IPs (Exchange IP and client IP). Can anyone explain the reason for this to me, please?

• Software Diagnostics Tool recommendations for Debugging a Windows 8 freeze

  - by Stuart

  I've had my HP Pavillion dv6 laptop since last November - and it has had 8GB RAM and a 256GB Crucial M4 SSD installed since the start. I use it for software development and it's had a Windows 8 RTM installation since early September. Yesterday I had to give a presentation at a customer site - so used Powerpoint for the first time since installing Win8... since that point my machine has 'frozen' every 2 hours or so after startup. There doesn't seem to be any easy to see reason behind the freeze - the system just freezes, even if I have left it idle with just a desktop there. My immediate suspicion is that the SSD is the mostly likely cause of the problem. I've looked at some of the questions on here - e.g. How do I troubleshoot hardware issues related to a computer freeze/crash? - but don't really want to start taking my laptop apart. Another suspicion is that this might be related to the WiFi adapter (Broadcom 802.11n) since I have noticed that this doesn't seem to play perfectly with things like Hyper-V in Win8. Can anyone recommend any software diagnostic tools that I can run in order to evaluate the health of the SSD or of other parts of the system? Thanks Stuart P.S. I doubt Powerpoint is the cause of this, but I may use it as an excuse never to use it again... More realistically perhaps something got damaged during travel to the customer site?

• No internet access when using static IP

  - by Endy Tjahjono

  I have just upgraded to Windows 8.1, and after the upgrade process is finished, I can't connect to internet. I tried running the "Troubleshoot problems": It concluded that DHCP needs to be activated: I let it activate DHCP, and I got internet connection back. The problem is I want to set this PC to a certain IP address (the IP address that it has been using all this time). I am also using Hyper-V, which I suspect has something to do with this problem. After I regained internet connection, I tried running one of my Hyper-V VM. From inside the VM I can connect to internet. That VM has static IP address. I also noticed that in "Control Panel\Network and Internet\Network Connections", I usually have a network connection called vEthernet (Realtek PCIe GBE Family Controller Virtual Switch). I didn't find it there after upgrade. How do I set my PC to a static IP while retaining internet access in Windows 8.1? EDIT I have managed to recreate vEthernet (Realtek PCIe GBE Family Controller Virtual Switch) by unchecking Allow management operating system to share this network adapter in Hyper-V's Virtual Switch Manager and then checking it again. But when I changed the adapter to use static IP, it still can't connect to internet.

• Computer won't go into standby

  - by Robert

  When I select Start-Turn off computer-Standby the 'turn off computer' option window closes, and then nothing else happens. I can start new applications, and Windows acts like I never selected standby. I ran it for several hours after that. If I have a TV program scheduled to record when I select standby I get a window (the Pinnacle TV software) asking if I'm sure, there are programs scheduled to record - and the computer just keeps running after I select yes, never going into standby. I added that detail as it shows the standby process is starting. [This problem also happens if a TV program is not scheduled, so the scheduler task in not running/in memory. This problem happens regardless of whether I'm not watching TV. This problem happens regardless of whether Media Center is running (it usually isn't, I'm using Pinnacle to watch TV).] I looked at "How to troubleshoot hibernation and standby issues in Windows XP" http://support.microsoft.com/kb/907477 - ACPI is enabled, and "standby" is an option in "Power Options Properties." So it appears to be setup correctly. Windows XP SP3 Media Center Edition, all current updates installed.

• Specific DNS sometimes resolves to wildcard, incorrectly

  - by Mojo

  I have an intermittent problem, and I'm not sure where to start trying to troubleshoot it. In our dev environment, we have two visible IP addresses on load balancers, one to the front-end, and one to a number of back-end service machines. The front-end is configured to take a wildcard DNS name to support generic "portals." dev.example.com A 10.1.1.1 *.dev.example.com CNAME dev.example.com The back-end servers are all specific names within the same space: core.dev.example.com A 10.1.1.2 cms.dev.example.com CNAME core.dev.example.com search.dev.example.com CNAME core.dev.example.com Here's the problem. Periodically a developer or a program trying to reach, say, cms.dev.example.com will get a result that points to the front-end, instead of the back-end load balancer: cms.dev.example.com is an alias to core.dev.example.com core.dev.example.com is an alias to dev.example.com (WRONG!) dev.example.com 10.1.1.1 The developers are all on Mac OS X machines, though I've seen the problem occur on an Ubuntu machine as well, using a local cloud host DNS resolver. Sometimes the developer is using a VPN, which directs the DNS to its own resolver, and sometimes he's on the local net using a DNS resolver assigned by the NAT router. Sometimes clearing the Mac OS X DNS cache, logging into the VPN, then logging out of the VPN, will make the problem go away. The origin authoritative server is on zerigo, and a dig directly to their name servers always seems to give the correct answer. The published DNS cache time for these records is 15 minutes, but the problem has been intermittent for about a week. Any troubleshooting suggestions?
