  • Outlook locking network connection/session?

    - by HaydnWVN
    Scenario: We have an 'automatic orders' machine sat in the corner running XP with Outlook 2003. Its job is to check for new emails on a specific account, when it encounters one it checks the e-mail body for specific wording to determine which customer it is from (using a macro), then it checks the attachment for specific order codes before parsing the attachment to create a .csv file (which is then e-mailed onto one of the sales team) before importing the .csv into our bespoke ERP/Sales Order system to create an order. Problem: Periodically the machine will have symptoms of a lost network connection (unable to connect to any network source). Sometimes after several days, sometimes over a week. Volume of emails/orders processed does not seem to be linked. Additional info: The machines .pst is stored on a mapped network location. The .csv created is stored on a mapped network location. This is a workgroup, not a domain. All network drives are Samba shares from an Ubuntu fileserver. Our bespoke system runs from a database (MySQL) Ubuntu server. Our troubleshooting so far: I have switched machines (previous was Win2000) with the same symptoms. Restarting the machine FIXES the problem. Closing Outlook and then end tasking an Outlook.exe background process FIXES the problem. If you close Outlook, without end taking the background process, outlook will not reopen (saying it cannot find the pst file & it will not open any network location). Does Outlook have some kind of 'max session' linking it to network activity that is not closing after a mail request? Could Auto-archive be causing this? Is there a tool to check/display what each outlook.exe process is doing? Have not found many ways to troubleshoot this yet, as it is so infrequent...

  • RDP Connection to Windows 7 stays really slow

    - by Pavlo
    I have an Issue with connecting to Windows 7 via RDP. I can open an RDP Session, but regardless of any settings, the responce times are really long. This in particulary is the case when opening a web page in a browser. I've tried IE, Firefox and Google Chrome. I also use RDP connection to a Windows 2008 Server from the same client machine, and the speed is very normal with all features turned on. We have Gigabit Ethernet here. So I think it can not be the client's fault. What concerns Windows 7 Machine, I've tried shutting all the sraphic features off and turning the color levels to 256 colors. Result - the same. If I work locally on the machine - I can not see any lags. What else have I tried: Using old RDP 5 Client from Microsoft Setting network autotuninglevel as seen here Do You have some ideas? Thanks in advance! Update the problem seems to be with rendering window contents. All the window borders and pannes are rendered pretty quickly, but the content shows up very slowly. Also mouse movements are recognised by the Win 7 box only after some period. Are there some hidden settings in the RDP, where one could turn some advanced features off or turn some caching on? I use Bitmap Caching, but this apparently doesn't help.

  • Run a script on user connection on the VM host

    - by Scott Chamberlain
    I have a server running a Virtual Desktop Managed Pool, what I would like to do is when a user logs in I would like a script to check the number of available VMs and if below a threashold add additional VMs to the pool. The script to check the load and add to the pool is not the problem, I have that already figured out: $collectionName = "Test1"; $rdvh = "vmHost.example.com"; $minAvailableVMs = 2; Import-Module RemoteDesktop; $pool = Get-VirtualDesktopCollection -CollectionName $collectionName; $availableVMs = $pool.Size - ($pool.Size * $pool.PercentInUse / 100); $status = Get-VirtualDesktopCollectionJobStatus $collectionName #only add new servers if we are below the threashold and in the JOB_COMPLETEED state if($availableVMs -lt $minAvailableVMs -and $status.Status -eq [Microsoft.RemoteDesktopServices.Management.VirtualDesktopCollectionJobStatus]::JOB_COMPLETED) { Add-RDVirtualDesktopToCollection -CollectionName $collectionName -VirtualDesktopAllocation @{"$rdvh" = 1} } The problem I am having is, how do I run the above script on the Virtualization Host/Connection Broker/Some other server when a user connects?. I don't think it would be appropriate to run this as a logon script inside the VM, I think there is a way to do this on the management side but I don't know the new scripting interface in Server 2012 R2 well enough to know which commandlets I should look for to schedule this. EDIT: I know System Center is perfect for this but I do not have a license and was denied when I asked for it to be added to the budget.

  • Nginx proxy to IIS Connection Timeout

    - by MitMaro
    I am having an issue with random timeouts with a Nginx proxy connecting to an IIS machine. I have been watching a packet capture between the two servers and it seems that the IIS machine is receiving a SYN packet but is not responding with what I think should be an ACK response. Before the timeout occurs there seems to be a slower response from the IIS server. There is no unusual memory or processor usage on the IIS or Nginx machine. Some information on the servers and setup: Nginx Machine: Ubuntu 10.04 64bit Nginx 0.7.65 Amazon EC2 Windows Machine: Windows Server 2008 IIS 7 ASP.net Application in Integrated Mode Nginx Error: 2011/01/10 17:57:40 [error] 8297#0: *30 connect() failed (110: Connection timed out) while connecting to upstream, client: 209.***.***.***, server: secure.example.com, request: "GET /a/path/deliver.aspx HTTP/1.1", upstream: "http://***.***.***.****:****//another/path/deliver.aspx", host: "secure.example.com" WireShark Packets 6521.449528 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477422103 TSER=0 WS=7 6524.443239 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477422403 TSER=0 WS=7 6530.443241 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477423003 TSER=0 WS=7

  • Slow connection to Linux MySQL from Windows only (XAMPP)

    - by Josh
    I'm having a problem with a PHP project (using Kohana 3.2 framework) on my Windows 7 64-bit machine connecting to the database. The development database is stored on a Ubuntu Linux server on the local network. Other development machines running OSX and Linux are connecting fine. There are no other Windows development machines to test with. I can access MySQL fine using MySQL Workbench, and other projects (which I believe to be less database heavy) run mostly ok, only occasionally getting timeout messages. I'm constantly getting Maximum execution time of 30 seconds exceeded when functions such as mysql_query() are run in this particular project. Specifically, the Kohana file where the timeout occurs is MODPATH\database\classes\kohana\database\mysql.php [ 186 ]. My local set-up is: Windows 7 Professional 64bit XAMPP 1.7.7 (PHP 5.3.8) The output of uname -a of the Linux server is: Linux peach 2.6.38-11-server #50-Ubuntu SMP Mon Sep 12 21:34:27 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I've tried the following, with no success: Disabling Windows firewall Switching between using a persistant and normal connection In my.cnf, adding skip-name-resolve Increasing wait_timeout Enabling bind-address I've run out of ideas now, and have no idea how to debug an odd issue like this. Has anyone come across this before, or have any idea how I could find the root of the issue, or what might be the problem?

  • Without an internet connection my computer loads programs slowly. With an internet connection they load quickly

    - by Peter pete
    Gday. I've a laptop, with 8gb of RAM and a Samsung 830 SSD with about 2/5th of free space out of its 256gb. Win7 64b. Laptop is a Toshiba T130. In the other day I noticed that it took a long time to load a program, for example the python interpreter at the time the computer didn't have access to the home network. In both cases the computer boots quickly. About 40 seconds. Without internet opening the python interpreter, or notepad2.exe, or any program individually takes around 10 seconds. With internet connection (through WiFi) opening the same programs takes about 2 seconds. In both cases, it becomes SSD-instant-quick to open a program from a cold boot. I don't have any network mapped drives. I've tried with AV off (Avast antivirus) and same effect. I've installed all MS updates. I've googled and googled and have found nothing of help. I've run the Samsung SSD magician to "optimise" ssd and that didn't help. What could I do to determine & fix this issue?

  • Why am I experiencing random connection timeouts? (CentOS)

    - by Ryan
    I have a CentOS server setup that currently hosts several websites (all relative of each other in some form or another). As of recently throughout the day at the most random times the website speed will lag to a crawl and eventually hit a connection timeout. When I say random times this typically happens anywhere between 10am and 1pm usually, however, this morning this happened to me at 8am. I do not have a lot of familiarity with server knowledge as far as what I am looking for in this situation. What are some possible causes of why my server is slowing the websites down to a complete crawl or timing out? Are there specific things I should be checking for when this happens? I have noticed using: tail /var/log/httpd/access_log That usually when this down time occurs there are lot of IP addresses related to BingBot, Googlebot, and sometimes various bots or spiders that I am unfamiliar with. Could this be related and if so how can I avoid this from causing my websites to lag out? Thanks in advance for any help or advice. The websites that are timing out are built with PHP and use a MySQL database to display information.

  • Random “Lost connection to MySQL server at 'reading initial communication packet', system error: 0”

    - by user1606545
    Sometimes I get the error from MYSQL server: Lost connection to MySQL server at 'reading initial communication packet', system error: 0 I cannot find the cause, since most of the time it works, but every week for some hours I get this error. I googled, but there seem to be only users which have this error permanently. But in this case, it only occurs sometimes. I checked hosts.allow and hosts.deny, but the host is allowed and not denied. Also sometimes I get the error: File './database/table.MYD' not found (Errcode: 24) It occurs very rarely. But it occurs for some hours once a week, sometimes on multiple days, but suddenly the problem disappears again. I have checked the open files limit. It's 2048 and should be absolutely enough. I also tried to increase the number of open files nevertheless, but no effect. I thought, perhaps the process does not close some tables. But this is impossible, because after a while everythings o.k. again and the process opens maximum 100 tables at once. I also checked the MySQL-runtime-environment, and there were 930 opened files. I cannot explain that. After a while it's 129. I am running a MySQL-Server on a SUSE-Linux machine. I connect to the MySQL-Server from another host by the command line tool "mysql" and by MySQL-C-connector. The MySQL-Server is version 5.0.67.

  • New router, slower internet connection?

    - by qwerty
    So, we just bought a new router a few hours ago, and it does work. However, for some reason the speed is just ridiculously slow (compared to before, at least)! If i run a test on speedtest.net i get the following results: http://i.imgur.com/68JyH.png which are pretty good. But for some reason it's like the connection just "hangs" for a second when i navigate to a site through the browser (have tried different browsers). It's not on all sites, it kind of happens randomly. I think the browser cache might be speeding some sites up, because if i visit a site that i HAVEN'T visited before (since i cleared my cache), it takes like two seconds (if not more) to open the site. If i have visited it, it opens directly (it barely loads). Not sure what to do, really. Any suggestions on what might speed it up? Any settings i can play with in the router settings? The router is of the brand Belkin. I'm not sure about the model though, it says "Belkin, Play Max Wireless Router" on the box? Thanks in advance! EDIT: Alright, it takes a lot more than two seconds. At least 3-4 depending on the site. Any suggestions?

  • Troubleshooting my internet connection

    - by Simon Verbeke
    While I was out of the house, my father rearranged the network cables a bit. I don't know what he has done exactly - He says nothing more then pulling and untangling. When I came back home, my internet connection changed its IP from 192.168.0.205 to 169.254.197.233. The speed changed from 1Gbps to 10Mbps. It has also been at 100Mbps for a while. My subnetmask changed from 255.255.255.0 to 255.255.0.0. The standard gateway changed from 192.168.0.1 to no standard gateway. My DNS servers remain the same. I have checked the lights of the UTP ports, and it looks like it's only sending a heartbeat every few seconds. A sketch of the (relevant part of) the network: My PC ----- extender ----- modem ^ ^ ^ Wired | Wired | This thing connects two cables to each other All the cabling is gigabit, my network card is a Realtek RTL8168C(P)/8111(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20). THe modem is a CBN SVG6540E I have no idea what is going on here and I don't know how to find out either. Any help is welcome! If you need any more info, please ask.

  • No network connection for vmware esxi guests

    - by JavaDev
    I'm new to VMware and setting up an Esxi server as a trial with the intention of possibly virtualizing some of our servers in the near future. I have setup ESXi on a Dell poweredge server, and installed a Centos 5.6 and Ubuntu 11.04 guest os on the server. However I cannot get networking on my guest OS's. The host is connected to a network with a DHCP server via a switch and is configured with a static IP. I have the default set-up for networking on the host: both guests are connected to the default vmnic1 adapter via the virtual switch vSwitch0. One thing though, the virtual adapter shows 'Observed IP ranges' to be XXX.XXX.XXX.194-XXX.XXX.XXX.195 (I've blanked out the initial prefixes) i.e just 1 address, even though the network the host is connected to has the usual 255.255.255.0 subnet mask. On the guest machines (using DHCP) by default, I can see an eth0 interface but with no connection or assigned IP address. A physical machine connected to the network gets a DHCP lease as expected. How do I get networking working on my guest OSes? Apologies for the long-winded question.

  • VOIP and internet connection speeds [cable vs. fiber]

    - by microchasm
    Our office is migrating to IP telephony. We have less than 10 employees that will be using the phones. We currently have cable internet, and they just bumped the speeds: There is a data center that was just recently built in our building, and we were considering co-lo'ing there in the near future. As a result, they offered us access to their triple-redundant internet, but it's quite expensive. They are offering 3mbps committed with up to 10mbps burst for $250/month (discounted). We pay ~$120 for our cable (which the plan was to keep--at least for TV). I want the phone system and LAN to be as separate as possible. Was thinking about keeping the cable for LAN, and using the other connection for the phones (until I saw the price). Now I'm thinking it might make sense to add on to our existing cable setup, and change our phone to only have DSL as a backup for the cable. Is there any real benefit to the fiber? Especially for the price? Any other suggestions or ideas? Thanks.

  • Sudden "No Signal" in HDMI-DVI connection

    - by nazikus
    Yesterday I have connected external display Asus VW192C to my laptop Dell XPS 14-L421X via HDMI-to-DVI-D cable. And it worked perfectly fine from start. The day after, Asus screen went blank showing "No signal". Every time I connection/disconnection cable or power off/on the display it says "No signal". And I didn't change any system configurations meanwhile. To troubleshoot the problem, I have tried to connect laptop to TV (hdmi-to-hdmi) - it was fine. I've tried to connect a different laptop to the display via the same cable - worked fine as well. So its obviously something on system level, either Windows or graphics drivers. Also it seems that Windows still see the external display (I can move mouse pointer away from the main screen in Extended mode), but there's just no signal. Any ideas? What else to try? PS. My laptop has 2 graphics cards - GeForce 630M and Intel HD 4000 using NVidia Optimus technology. I have updated to latest Intel and NVidia drivers, still didn't help. PPS. Although I shouldn't have updated (from Intel support): "our Intel generic graphics drivers from the Intel website do not support using both Intel Graphics 4000 and NVidia GeForece GT630M". Nevertheless, it should not affect connectivity to additional display.

  • Subversion: Secure connection truncated

    - by Nick
    Hi, I'm trying to set-up a subversion server with apache2/webdav access. I've created the repository and configure Apache according to the official book, and I can see the repository in a webbrowser. The browser shows: conf/ db/ hooks/ locks/ Although clicking any of those links gives an empty xml document like: <D:error> <C:error/> <m:human-readable errcode="2"> Could not open the requested SVN filesystem </m:human-readable> </D:error> I've never used subversion before so I assume this is correct? Anyway, when I try to connect via a command line client, it asks for my password, I give it, then I get the (useless) error message: svn: OPTIONS of 'https://svn.mysite.com': Could not read status line: Secure connection truncated (https://svn.mysite.com) The command I'm using is: svn checkout https://svn.mysite.com/ svn.mysite.com Subversion was installed using Ubuntu's package manager. It's version 1.6.6 on Ubuntu 10.04.

  • External HDD connecting via USB disconnects wireless LAN connection

    - by Kensai
    Strange problem. I have this MEDION Akoya PC that has a dedicated bay to slide an external HDD sold separately. It's very handy indeed cause the slot is providing a fast USB 3 connection and power to the HDD unit, without extra cables. All works fine except this show-stopper behavior to disconnect me from the router once I slide in the unit and it powers up. The moment I connect the unit the (normally) three-four WiFi connections I see in my neighborhood disappear and my own to the router loses its signal strength (no Internet traffic is possible). After a while it throws me off that one as well, never to connect me again as long as the unit is powered. Once I disconnect the HDD the various signals come back and it automatically reconnects to my own. What takes? Are we in front of a serious design fault by MEDION here? Does the spinning of the HDD on top of the PC cause electromagnetic interference strong enough to throw off my WiFi connectivity? Is it a simple USB problem? Some kind of strange hardware conflict? Where should I look?

  • Win7 loses connection to network shares after resume unless server specified using FQDN

    - by Szonja Zemkó
    My Win7 client has a connection to a Linux server and its shared folders. The problem occurs when the computer wakes up after a sleep and then one of the shared folders is not accessible. I receive the following message: Error code: 80070035, The network path was not found. I have problem with one specific folder only. When I restart the computer this problematic folder is accessible again. When I log off before sleep the folder is accessible after wakeup. If I try to access the folder by using the FQDN of the server or the server IP it is also accessible. As a temporary solution I mapped the folder to a network drive using the FQDN and it's working fine but it's inconvenient since every other folder is accessible on the server. To summarize: \server\problematicshare no longer works after resume (the Samba server sees my client connect, then disconnects a few seconds later while I receive the above error message) \server\othershare works after resume \fqdn.of.server\problematicshare always works \ip.of.server\problematicshare always works once the problem manifests, I'm no longer able to restart the "Workstation" service (it is not responding) restarting the "Computer Browser" service has no apparent effect the event log doesn't contain anything that seems relevant "ping server" works

  • How to fix "The connection was restarted"?

    - by Altar
    I have a php script with ajax. Few days ago, without making any changes, the script stopped working. The script is working sometimes but it is very slow. Other times it doesn't load completely. Yet other times it loads and empty page or it shows a "The connection was restarted" message. We have tried loading the page from 4 different computers in two different countries (two different ISPs). There is nothing relevant in the server's log. We contacted iPage.com hosting support. We sent screenshots. And all we manage to get from them was an incomplete screenshot and the message 'We tested. The page loads'. So, they won't admit the fault. It looks like they loaded the page once and declared it is working and went back to playing solitaire. I know their support. We had all kind of problems with iPage hosting. My questions are: 1. There is any way to make this error more easy to reproduce? I mean instead of fixing the error to get it appear more often. 2. There is any way to test a server response, to see if it drops connections?

  • Strange 3-second tcp connection latencies (Linux, HTTP)

    - by user25417
    Our webservers with static content are experiencing strange 3 second latencies occasionally. Typically, an ApacheBench run ( 10000 requests, concurrency 1 or 40, no difference, but keepalive off) looks like this: Connection Times (ms) min mean[+/-sd] median max Connect: 2 10 152.8 3 3015 Processing: 2 8 34.7 3 663 Waiting: 2 8 34.7 3 663 Total: 4 19 157.2 6 3222 Percentage of the requests served within a certain time (ms) 50% 6 66% 7 75% 7 80% 7 90% 9 95% 11 98% 223 99% 225 100% 3222 (longest request) I have tried many things: - Apache2 2.2.9 with worker or prefork MPM, no difference (with KeepAliveTimeout 10-15) - Nginx 0.6.32 - various tcp parameters (net.core.somaxconn=3000, net.ipv4.tcp_sack=0, net.ipv4.tcp_dsack=0) - putting the files/DocumentRoot on tmpfs - shorewall on or off (i.e. empty iptables or not) - AllowOverride None is on for /, so no .htaccess checks (verified with strace) - the problem persists whether the webservers are accessed directly or through a Foundry load balancer Kernel is 2.6.32 (Debian Lenny backports), but it occurred with 2.6.26 also. IPv6 is enabled, but not used. Does the issue look familiar to anyone? Help/suggestions are much appreciated. It sounds a bit like a SYN,ACK packet getting lost or ignored.

  • Methods and practices for managing a network that has no internet connection

    - by FaultyJuggler
    Originally asked in Super User but realized this belongs here. Long story short, I am setting up a network with 32 servers of varying specs that will be used for testing and development. We will be using RedHat Linux, we also do not have a router as of yet and were looking into making one of the servers act as our router/DHCP etc. The small cluster will be on an isolated network with no internet. I can use external harddrives and discs to transfer anything from external sources into machines on the network, so this isn't a locked down secure network, it just won't have a direct connection to the outside world. I've worked on such setups before, but always long after they were setup. So I'm reaching out to see what everyone knows as far as how groups have handled initial setup and maintenance of such a situation. What is the best way to get them all configured and up to date? What are the best ways to automate updates, network wide installs, etc. With the only given that I have large multi-terabyte external hard drives that would be used to drop whatever files are needed onto a central server, how do i then distribute those files and install their contents? I've done perl scripting, some teammates have played with puppet, so we aren't completely in the dark, I just wanted to avoid reinventing the wheel since this is a common challenge.

  • Flat File Connection Manager in SSIS package shows "Valid File Name Must be Selected"

    - by Traples
    (Flat File Location) Samba Share | Windows Share (SSIS) _______________________________ | | XP 32bit | Works | Works | | 2003 Serv 32bit | Works | Works | | Vista 64bit | ERROR | Works | | Win 7 64bit | ERROR | Works | | 2008 Serv 64bit | ERROR | Works I created an SSIS package in VS 2008 that parses a flat file from a shared folder and puts the records into a SQL Server db. I recently installed Windows 7 and VS 2008 on a new workstation. When I import the package from TFS and open it, I get the error Validation error. Parse and Import Catalog Flat File: MySSISPackage: The file name "\\shared\flatfile.txt" specified in the connection was not valid. When I open the Flat File Connection Manager Editor, there is an error stating: A valid file name must be selected I can browse to and select the file from inside the editor, but I cannot change any properties, or move away from the General tab because of this error. If I go back to my laptop (Windows XP), where the package was first created, there is no error. Both workstations are on the same domain, and I'm logging in using the same credentials. Any ideas as to why I would receive this error from one workstation and not another? UPDATE: If I take the .dtsx package from the running workstation and load it into SSIS on the server, I get the following errors when it tries to run: Error: The file name "\\shared\flatfile.txt" specified in the connection was not valid. and... Error: Connection "MySSISPackage" failed validation. and... Error: The file name property is not valid. The file name is a device or contains invalid characters. UPDATE 2: a) The Shared folder I'm trying to pull the flat file from is a Samba share on a Unix box. b) If I access the file using SSIS on any 64-bit platform (Windows 7 64-bit, Vista 64-bit, Windows Server 2008) I get the error "A valid file name must be selected." c) Accessing the file using SSIS from 32-bit environments (Windows XP 32-bit, Windows Server 2003 32-bit) there is no problem. d) If I move the file to a shared folder on a Windows server, 64-bit SSIS recognizes the file.

We use ODP.NET from ASP.NET applications, and we suspect the firewall closes connections that have been in the connection pool too long. Sometimes we get an "ORA-12571: TNS packet writer failure" error, and sometimes we get "ORA-03135: connection lost contact." I was wondering if someone has run into this and/or has an understanding of the difference between the 2 errors.

    I'm using NHibernate with SQL Server 2005 in a WPF client application. If I stop the SQL Server service and then restart it the session doesn't automatically reconnect. So far I'm doing this witch seems to work : try { using (ITransaction transaction = this.Session.BeginTransaction()) { // some select here } }catch(Exception ex) { if(this.Session.Connection.State == ConnectionState.Closed) { try { this.Session.Connection.Open(); } catch (Exception) { } } } Is there a better way ?
