• USPTO site asks for Quicktime Plug-in which I already have installed. Why?

  - by Kensai

  Whenever I try to watch the images of a patent in the USPTO site (example) using Firefox, the browser asks me to download the latest Quicktime, manually. This is totally strange because I already HAVE the latest plug-in (it even appears on my Firefox add-ons list). In the past I have only been able to see patent images using Safari. But never with Firefox. Is it a USPTO problem or a Mozilla one? Is there a way to fix the problem? edit: I can't see TIFF images neither with Internet Explorer (both 32-bit and 64-bit versions) nor with Chrome. All these browsers don't know how to open embedded TIFF images because they don't recognize the installed Quicktime plugin. A USPTO conspiracy to promote Safari? Come to think of it, I had this problem in my old computer as well. It had a 32-bit Vista OS, now I have 64-bit Windows 7. I hate TIFF and can't find Mozilla-specific information anywhere.. Arghh, am I the only one here with this freak problem?!

• Problems with Windows 7 restore

  - by Chris Lively

  My WD raptor 150 failed with a nice clicking noise. So, I picked up a velociraptor 300 and popped it in. I had windows set to do a full system backup nightly, so I figured the recovery ought to go easily. Well, it isn't. It is currently stuck on a screen that says: "Windows is restoring your computer from the system image. This might take from a few minutes to a few hours" Below that is a rather large progress meter with maybe the first block filled in. Below that is a message that says "Restoring disk (C:)..." It's been that way for over an hour. The first time around, I gave up after 2 hours. I then booted into the system recovery options and went to a command prompt and ran a chkdsk on the new drive. It showed several file inconsistencies and not much else. I ran a chkdsk /f on it and tried again... Which is where I'm at now. I can't see that the restore process should take this long before. Any ideas? UPDATE After 10 hours, it's still on "Restoring disk (C:)" and the progress meter is at roughly 5%. I'm guessing at the 5% as there isn't an actual number or anything else that I can look at showing what it's actually doing. The backup contains roughly 120GB of data. How slow is windows restore?

• Looking to replace Ghost with FSArchiver or Clonezilla, few questions about capabilities

  - by Daniel Wright

  I work for a PC Repair company and we are looking into setting up a dedicated machine with externally accessible SATA bays to clone harddrives as a safety net incase something goes wrong during a repair. We currently use a SATA/PATA to USB bridge called MagicBridge and Norton Ghost on any workstation, but we're looking to move away from Ghost. We have a computer with a large RAID5 array with Windows Server 2008 Standard currently installed, but this can be replaced with a flavour of *nix. I have some experience with Clonezilla, but FSArchiver also seems like a suitable replacment too. My Head Technician wants to know if my chosen solution (probably Clonezilla or FSArchiver, but I'm open to free suggestions) is capable of: Cloning a degraded RAID, such as a single drive from a RAID1 mirror without complaining Producing images that are easily mountable (he'd prefer them to be mountable in Windows, but if there is no other easy way, *nix should be fine) akin to Ghost Explorer so individual files can be restored as well as being able to do bare metal restores. My apologies for wordiness but I wanted to be thorough in my explaination. Thanks for any suggestions or tips :) EDIT: I've just found out that Clonezilla has a workaround for cloning RADI1 drives EDIT2: Found the answer to both of my questions, aparently I wasn't phrasing my searches right, could this question be deleted please?

• Sending Mail from Web App to Google Apps won't work - internal routing? VPS

  - by Charlino

  I've got a web application, www.mysuperwebapp.com, which sends out emails for various reasons - the contact us page is a good example. I am using google apps on the domain and I've setup a google apps group, Support ([email protected]), which I want the emails from the contact us page to go to. But the emails don't seem to be sending... I thought it could be that the groups security is a little tighter than normal email, so I change the contact us email to go to [email protected] - but they still didn't appear. So I'm guessing that it has something to do with internal routing and the messages aren't leaving the server/network at all. Eg Sending an email from the mysuperwebapp.com computer to a mysuperwebapp.com email address. I put an entry into the hosts file for 123.123.123.123 mysuperwebapp.com but that doesn't seem to have helped. Also, there doesn't seem to be anything of interest in the event log. What do I need to do? Or what do I need to get my VPS hoster to do? TIA, Charles Ps. The VPS is a Windows 2008 box with IIS7 and the default SMTP (IIS6?) server. The web app is ASP.NET MVC - not that that should matter.

• DLINK WBR-1310B Wireless Router seems to hang...

  - by Ira Baxter

  I have a brand new DLINK-1310B Wireless Router (box never before opened, although I bought it the neighborhood computer junk store). I am using it at home (and in fact am using it this instant from a wireless laptop). When operative, I can ping it at 192.168.0.1, and I can log into it from the PC attached to by LAN and from the wireless PC at //192.168.0.1. In the course of the day since I've installed, it seems to have locked up 3 times. Each time the symptoms are my web browser (or other internet service) stops with a "No internet connection" error. Attempts to contact the router via 192.168.0.1 get no reaction, from either the wireless laptop or from the hardwired PC sitting next to it. It doesn't respond to pings to that address either. Rebooting fixes it. Its brand new. I've seen discussion in other questions about aging cheap electronics. Its too new to be aged. Anyboyd else seen this behavior with a DLINK-1310? Or do I just need to exchange it for another and try again? (I hate rolling dice, I bought the DLINK becuase a previous Linksys died of apparant heating problems). Remarkably, nobody talks about how much software is in a router. Is the stuff just buggy?

• Loss of network connectivity when playing video on Optoma HD180 projector

  - by Jeff Fohl

  Hi Folks - New to Super User, so I hope this question fits in with the guidelines. Very strange problem I am having, and I am at a loss as to how to continue troubleshooting this one. The basic problem is that when I attempt to watch streamed video on a particular display device (an Optoma HD180 projector), my network connectivity drops like a stone to barely measurable levels. This is my setup: I have a Dell H2C 730x running Windows 7 64bit. This particular computer has two ATI Radeon HD 4800 video cards. I have two Samsung 22" monitors connected to one card, and an Optoma HD180 digital projector connected to the other card via an HDMI cable. My internet connection is normally a reliable 6Mbps. The problem I am having occurs when I stream video (or even just browse the web) on the Optoma Projector. When I do this, my internet connection drops to practically zero (just a few kilobits per second). When I move the browser away from the projector, and over to one of my Samsung monitors, the internet connection comes right back. Note that the Optoma projector is on and enabled as a third monitor all this time. I can move the mouse around on the projector without triggering the problem. I tried pinging my router when I was playing a movie on one of the monitors, and I get a 1 millisecond response. However, when I have the movie playing on the Optoma projecter, pinging the router gives me response times in the hundreds of milliseconds, or times out completely. So, it clearly is something local to my machine - and not some sort of throttling occurring down the line. I would think that it is possibly something to do with the HDMI driver conflicting somehow with my network driver (which is a USB-based wireless connection). This one has me really stumped. Anyone have any ideas?

• Mac computers unable to connect to samba

  - by tan-ce

  I have a Ubuntu 9 server with samba 3.3 installed. This server has two network interfaces, one to a "public network" which I do not have any control over and another to a private LAN. On the private LAN, samba is the Domain Controller and nmbd is the WINS server on that network. On the "public network", I have configured a second instance of nmbd to run as a WINS client. The setup seems to work fine for Windows XP (on the domain or otherwise) as well as other Ubuntu machines. Finally, my question: Mac computers seem unable to connect to the samba server. As far as I can tell, it is as if samba is invisible to the MAC computer. Could my configuration of nmbd be causing this problem? Or is this simple a Mac oddity and is there anything I can do about it? New updates/info: We tried to connect through the Finder - Connect to Server, we entered smb://servername where servername is the netbios and DNS name. (There is also a DNS entry for the same name on the network) We also tried connecting by IP address Also, I just realized that there is at least one Mac which can connect. (Leopard 10.5.8) I will try to get the Mac OS versions of the computers which couldn't connect as soon as I can. The Mac which could not connect was running Mac OS X 10.4.11. Was there a change to samba on Mac OS between 10.4 and 10.5?

• Group policy not applying to security group

  - by ihavenoideawhatimdoing

  Preface: I have enough privileges to create GPOs in my OU, and have made a few of them for some simple tasks (like deploying a printer to certain users). Not actually a sysadmin...I'm a developer who is winging it. I wanted to create a GPO that would set a mapped folder for a certain security group (which I recently created and that contains only myself). Did the following: Created the GPO in MyOU - Users Removed the default Authenticted Users under Security Filtering Add the security group with my account to Security Filtering Set up the mapping via the User Configuration option Changed GPO Status to "Computer configuration settings disabled" Left WMI filtering to Closed the GPO at this point... Logged in as the target user; ran gpupdate /force Logged out, logged in, ran gpresult /r, no mention of my GPO Rebooted Logged in, re-ran gpupdate /force Logged out, logged in, ran gpresult /r, still no mention of my GPO If I log in with another completely different user, their RSOP information shows that the new GPO is being ignored due to a security restriction, so it appears to be "working" for other users. I just can't get it to actually show up in RSOP for the user it should be working. Is there anything else I can do short of rebooting endlessly and crossing my fingers?

• Software way to cool down an old MacBook Pro

  - by notMacBookProSuperUser

  Hi all, First a little background: I've got lots of computers, including Linux PCs and two MacBook Pro (and a MacMini). My concern is with my 'old' MacBookPro (Core Duo). It really does overheat. Warranty is long void. Years ago (I'd say 2.5 years ago or so) one day it overheated so bad that the battery inflated due to the heat. I got a new battery for free but it's still getting incredibly hot (much other than any other computer I've got: my newer Core 2 Duo MacBook Pro doesn't get nearly as hot as the old one. It s really a pain because I use my old MBP when I m in front of TV, having it on my lap, and it can really become unbearable. I don't want to open that old MBP. On Linux I can force a new CPU 'governor' that decides how the CPU is allowed to operate: it can be 'on demand', 'always max speed', 'always speed x', etc. Does the same exist under MacOS X? Is there a way, say if a 1.86 Ghz Core Duo can run at 1.6 Ghz, to ask MacOS X: "never run this CPU above 1.6 Ghz" ?

• Trying to run a codeigniter app on custom php

  - by hamstar

  I have a CodeIgniter app that I deployed to a server with php 5.2 and my dev box has 5.3, and some stuff doesn't work anymore. I didn't want to upgrade php and risk the other app on the server having issues. Anyway I compiled a custom PHP and added the following to a single .conf file in /etc/httpd/conf.d/zcid.conf with all the other conf files. <VirtualHost *:80> DocumentRoot /var/www/cid/app ServerName sub.example.co.nz </VirtualHost> <Directory "/var/www/cid/app"> authtype Basic authname "oh dear how did this get here i am no good with computer" authuserfile /path/to/auth require valid-user RewriteEngine on RewriteCond $1 !^(index\.php|robots\.txt|createEvent\.php|/cgi-bin) RewriteRule ^(.*)$ /index.php/$1 [L] AddHandler custom-php .php Action custom-php /cgi-bin/php53.cgi </Directory> In /var/www/cid/app I have the cgi-bin folder and the php53.cgi that I copied from /usr/local/php53/bin/php-cgi But now when I navigate to the subdomain it says: The requested URL /cgi-bin/php53.cgi/index.php/ was not found on this server. And if I try to browse to /cgi-bin it says (what it is supposed to?): You don't have permission to access /cgi-bin/ on this server. Quite confused now. Anyone know what to do here? Thanks :)

• Why is my biometric logon method no longer default and how to fix it? Win 7-based lenovo laptop

  - by StormRyder

  My laptop has been having some random problems with hibernating properly. That is a whole another topic that I still haven't resolved, but this is a different issue. The issues are connected, I guess, because one time after my computer experienced a failed hibernate, my login screen changed: since then my login screen always appears as the standard one with a prompt to type in a password. I can still use the finger scanner by clicking "other credentials" button. But that's annoying having to do that every time; previously the prompt to use finger scanner was the default one, whereas the typing password access was the alternate. How do I bring this arrangement back? In other words, how to switch the default from the type password prompt to the finger scan prompt? From online searches, I have only found discussions of turning the biometric access on or off... but clearly it is turned on and working, since I can use it. It's just not the default for some reason...

• How to Load Balance 2 Internet Connections on a Windows 7 machine?

  - by Jimmy Chandra

  It's sort of related to this particular question, but that one is on Mac. I am looking for similar solution on Windows 7. I have 2 network connections: (Connection A) Wireless terminal connecting to ISP A (3G / EVDO internet provider) (Connection B) Broadband wired connection connecting to ISP B (Cable internet provider) Both has access to the internet. When I try connecting to a website and checking the networking tab on my Task Manager, I only see the network traffic being routed to only Connection A. Is there a way to make the computer to utilize both network (in a sense using all the bandwidth available from both the Cable ISP and the 3G / EVDO ISP) at the same time? If so, what do I need to do to set this up ... on Windows 7? Here is a bit more info on my network connections (ipconfig /all): PPP adapter Wireless Terminal: IPv4: aa.bb.ccc.ddd(preferred) Subnet mask: 255.255.255.255 Default Gateway: 0.0.0.0 DNS: aa.ee.f.ggg aa.ee.f.hhh Primary Wins: jjj.ii.k.l Secondary Wins: jjj.ii.k.m Ethernet adapter LAN: IPv4: 192.168.1.100 (connected to a router by wired that itself connect to a cable modem) subnet mask: 255.255.255.0 Default gateway: 192.168.1.1 (the wireless router) DHCP: 192.168.1.1 (the wireless router) DNS: xxx.yy.zz.ww rr.sss.t.uuu For my own privacy, I don't believe the actual number matters, the patterns are representative of the ip numbering scheme...

• PHP sessions currupt

  - by Baversjo

  Using symfony framework 1.4 I have created a website. I'm using sfguard for authentication. Now, this is working great on WAMP (windows). I can login to several accounts on different browsers and use the website. I have ubuntu server 9.10 running apache (everything up to date and default configuration). On my server, when I login to the website in one browser it works great. When I on my other computer login with another user account on the public website, the login is successful. But when I refresh/go to another page the first user is shown as logged in instead! Also, when I press logout, It's not showing that I'm logged out after page load. When I press f5 again I'm logged out. As mentioned, all this works as expected on my local installation. I'm thinking there something wrong with my PHP session configuration on my ubuntu server, but I've never touched it.. Please help me. This is a school project and I'm presenting it today :(

• How to Log Into a Web App Simultaneously with Different Account?

  - by Ngu Soon Hui

  I want to log into a web application, using at least ten account names at one single point of time ( I am not trying to do anything illegal, so don't worry). AFAIK, each tab in Chrome will share the same session, therefore, for one machine, one can use Google Chrome to log in at most 2 accounts, one in normal mode, another in Incognito mode. Is there anyway I can log into multiple accounts? I know I can open up IE and Firefox ( probably Safari etc) and login, but this is not really scalable as the number of web browsers is finite. Edit: My application is a localhost application; it resides on my computer. So proxy may not be that useful, and you now probably understand why it's nothing illegal. Edit2: CookieSwap seems like a good idea, but the problem is that once I swap the cookie, all the tabs and the FF apps' cookie are swap as well. Can the swapping be done on a tab basis or on application basis, so that on a dual-monitor, I can see the different login side-by-side?

• How can I recover my system after running 'mkfs' on the system partition?

  - by Filip Podgórny

  I am not a Linux user, and was doing some homework, I blindly typed sudo mkfs ext3 dev/sda2 (I had Ubuntu as Windows installation). I've done few more things, and turned Ubuntu off to switch on Windows back. No operating system installed - this is the message I'm getting.

• mysql INNODB inserts very slow

  - by 133794m3r

  The database's schema is as follows. CREATE TABLE `items` ( `id` mediumint( 8 ) unsigned NOT NULL AUTO_INCREMENT , `name` varchar( 45 ) NOT NULL , `main_type` tinyint( 4 ) NOT NULL , `rarity` tinyint( 4 ) NOT NULL , `stack_size` smallint( 6 ) NOT NULL , `sub_type` tinyint( 4 ) NOT NULL , `cost` mediumint( 8 ) unsigned NOT NULL , `ilvl` smallint( 6 ) unsigned NOT NULL DEFAULT '0', `flavor_text` varchar( 250 ) NOT NULL , `rlvl` tinyint( 3 ) unsigned NOT NULL , `final` tinyint( 4 ) NOT NULL DEFAULT '0', PRIMARY KEY ( `id` ) ) ENGINE = InnoDB DEFAULT CHARSET = ascii; Now, doing an insert on this table takes 0.22 seconds. I don't know why it's taking so long to do a single row insert. Reads are really really fast something like 0.005 seconds. With using the example configuration from here dev mysql innodb it averages ~0.002 to ~0.005 seconds. Why it takes more than 100x more time to do a single insert makes no sense to me. My computer is as follows. OS:Debian Sid x86-x64, Mysql 5.1, RAM:4GB ddr2, cpu 2.0Ghz dual core, HDD 7200RPM 32MB cache 640GB. Why it's taking almost 100x as much time for a SELECT * FROM items; vs INSERT INTO items ...; will never make any sense to me. It's still a small table at only 70 rows, and took that long even when it had 0 rows.

• OpenSolaris livecd, NForce NIC driver, and NTFS USB mounting. Oh My!

  - by Jake Wharton

  I'm attempting to install OpenSolaris 2009.06 on my server. Before I do I would like to test that everything works and am running in to problems. It has an Abit AN-M2 motherboard with an NForce chipset. The driver config utility says that I need a third-party driver and links me to http://homepage2.nifty.com/mrym3/taiyodo/eng/. Scrolling to the bottom, I have downloaded both tgzs just in case. Now the fun part: The only way to get this on to the computer is via a USB drive since I can't access the network. Also, install CD in the drive otherwise I'd just burn them to DVD. Since my USB key is NTFS formatted I cannot mount it since the install CD seems to be lacking NTFS drivers which require more downloaded packages. What should I do? The server will simply be a dumb NAS and I know that there exists other OpenSolaris-based flavors such as Nexenta but from what I read the stock install is likely the best. If this is not the case and pursuing a different flavor is required or better I will also accept that as an answer (but please don't jump straight to it).

• Troubleshooting: Monitor never turns on, system fans running, DVD-ROM does not open.

  - by Wesley

  Hi all, Here are my specs beforehand: ECS P4VXASD2+ (V5.0) motherboard FSB 533MHz Intel Pentium 4 2.40A GHz Prescott Socket 478 2x 256MB PC2100 DDR RAM, 2x 256MB PC133 SDRAM CoolMax 350W PSU DVD-ROM - will edit with brand & model 128MB ATi Radeon 9800 Pro AGP No hard drive So, I just put those parts together today and I tried to power it up, with the monitor connected to the Radeon 9800 in the AGP slot (mobo does not have VGA port). After turning it on, the CPU fan, graphics fan and system fan go on. However, the monitor remains in standby mode, despite being plugged in. Also, after pushing the button on the DVD-ROM drive, it does not open. I've used the DVD-ROM drive before with absolutely no issues. The graphics card was slightly buggy when I put it on another machine, which was left outside in winter weather for 3 months. (Still that computer's integrated graphics worked fine.) CMOS battery was replaced and jumpers are all set correctly. Now, I'm wondering whether the motherboard, CPU, PSU or GPU is the problem. What can I do to test which part is the problem? Just to clarify, I don't have a hard drive, so I usually boot Ubuntu from the disc drive. Anyways, thanks in advance!

• Connecting 2 different subnet masks

  - by Jonathan

  I'm no network genius, but I have managed to get most things running. I get confused about subnets and gateways though. We have an office server connected to around 20 PC's that all communicate fine. We have just gotten a cutting machine that won't connect to our network. The server has DHCP, but that fails on the cutting machine, so I've been trying to set the IP manually. Server details are as follows: IP: 10.1.1.12 SUBNET: 255.255.255.0 GATEWAY: 10.1.1.1 Internet connection is via the modem which is 10.1.1.1 An office PC is ussually set up through DHCP and has the following settings: IP: 10.1.1.36 SUBNET: 255.255.255.0 GATEWAY: 10.1.1.1 PRIMARY DNS: 10.1.1.12 Cutting Machine computer has 2 network ports. 1 is specifically for the communication between the PC and the cutting machine. It's details must be as follows: IP: 10.100.100.2 SUBNET: 255.255.255.252 GATEWAY: BLANK The other network port need to connect to the server. I was told that the IP and SUBNET need to be as follows: IP: 10.100.100.1 SUBNET: 255.255.255.252 GATEWAY: ?? How can I connect this port to the server and/or the internet. If anyone can offer assistance, it would really be appreaciated.

• Disaster recovery backup of files/photos for personal use

  - by Renesis

  I'm looking for the best method to store a backup of important files and 5+ years of digital photos that is safe from some type of fire/flood disaster in my home. I'm looking for: Affordable: Less than $100/yr or first-time cost. Reliable: At least a smaller chance of failing than there is of fire or flood Easy for initial backup and to add to, and at least semi-easy to recover. I recently purchased a small home safe for physical vitals. It was inexpensive, solid, and is fire/water safe. If I had a physical copy of the digital files, the safe would work fine for this, but I don't know what to store in it that adequately meets the requirements above. Hard drive - I read that the danger of it not spinning up makes a hard drive a bad choice for this type of storage, although it was my first thought and would definitely be the simplest choice - very easy to take out once a month and add files to. DVDs - Way too much of a hassle for both backup and restore. Tape - No idea on the affordability of this option Online - Given that I have at least 300GB already and ever-increasing megapixels means ever-bigger files, and my ISP upload is about 2Mb at the best, this just doesn't sound like a good option for me, but I could be convinced. Other - Have I missed something? Also, I'm already covered both for sync between computers (Dropbox) and a nightly backup of these files (External HDD). The problem with the nightly backup is obviously that it's always with the computer and in a disaster would be destroyed along with it. Is anyone else doing something similar? Is the HDD as poor of a choice as I read, or is it a feasible option? Maybe two to reduce the likelihood of failure?

• Filesharing mac 10.6 with windows vista

  - by adam

  Ive followed all the tutorials on the net to no avail. I can see my vista pc in finder on the mac but when I click on it tries to connect but fails. The same is true from vista, it can see the mac but i cant connect. Wont even offer a login box. So I tried to troubleshoot by using a 3rd computer with xp. It joined the network and can access both the mac and vista on the same workgroup. Mac sees it and it shows under finder but i cant access it by clicking on the icon i have to access by using the ip of the xp machine...strange. Ive turned off all my firewalls. The fact that xp can connnet to the others and vice versa boggles my mind why vista and mac cant connect directly. Oh and pings indicates the same. I.e. xp has no problem but mac to vista and vice versa fails. Can anyone help.

• How to test server throughput

  - by embwbam

  I've always used apache benchmark to try to get a rough idea of how many requests/second my server can handle. I read that it was good, and it seemed to work well. Enter node.js, which is fully event-based, so it never blocks. If I run apache benchmark on a simple hello world server it can handle 2500 requests per second or so. However, if I put a timeout in the hello world function, so that it responds after 2 seconds, apache benchmark reports a dramatically reduced throughput: about 50/s. I'm running 100 concurrent connections with ab. If I increase the concurrency, it goes up. This makes sense, because apache benchmark is basically sending out requests in batches of 100, which come back every 2 seconds. 100 requests / 2 seconds = 50 requests / second If I increase the concurrency to about 400 or 500, it starts to crash. I don't think I've hit node.js's limit, I think I'm hitting a wall in my operating system on the number of open file descriptors or sockets or something. Any way I can get a good guess about how many requests my server can handle? I want to make sure the test computer isn't the one causing the problem.

• Scriptable BitTorrent clients?

  - by James McMahon

  In an effort further automate all the little computer house keeping tasks that can waste my time I am looking into BitTorrent clients that have the ability to script common tasks. I've done some Googling and it looks like Transmission might have some of said such capabilities, but there site wasn't very clear on the details. Things I am looking to do; Prioritize and label torrents based on trackers Set seed length based on trackers and filesize Set additional seed time when a torrent's seed time expires based on a number of factors, like time spent seeding, remaining disk space and ratio. Move torrents to appropriate places post seeding based on labels and tracker Basically, while I could Python or Bash script things like moving torrents around and other simple actions, I need away to talk to the client to figure out things like the torrent seed time, tracker, labels, filesize, etc. Is there any client out there that would allow me to all or a subset these actions? I have access to Linux, Mac and Windows and am not tied to any particular torrent client. I am a programmer so I have no problems writing scripts, but examples of torrent scripting would also be helpful.

• Guest can't access host windows network share

  - by Asteroza

  HI folks, I've recently run into a strange problem after upgrading to VMware player 3. Certain virtual machines (currently an XP and a VIsta VM) seem to have lost the ability to access the host (XP) network shared folders (SMB). Both VM machines are bridged networking, firewall is up. Host firewall is up. Host and guests use DHCP. All OS are workgroup connected. The Vista VM I am not completely sure, but the XP VM did have access to the host's network shared folders after the player upgrade. Then today it wouldn't work, network path can't be found. Now here's the wierd part. The host's network shared folders can be accessed properly by other PC's on the network (and as far as I know, no settings have been changed). The host is pingable from the guests, and name resolution works. The guests can access network shares on other PC's in the network, and access the internet. My Network Places shows the host PC, but double clicking on it takes a long time before it finally times out with an error. Doing a wireshark packet capture, the guest is sending out the protocol negotiation, and the host is sending a response, but after that the guest behaves like it didn't receive anything and is doing TCP retransmissions. Anybody have any idea what could be wrong? Yes I know I can drag and drop files or setup the special VMware shared folders, but I want to access the host just like any other network accessible shared folder. It just seems really odd when any other computer works, just not between the guest and host.
