• Do TCP/UDP connections add to the Windows incoming connection limit?

  - by user47899

  Hi all, I've tried to figure out what Microsoft means by "Windows sockets" and it all seems very vague. Basically we have customers that sometimes try to set up workgroups with close to 10 Windows XP computers with drive and printer shares and we're worried that some of the non-Windows Ethernet devices on the network will cause issues with the inbound connection limit outlined here where only 10 inbound connections can be active at one time. For example, there is an Ethernet Caller ID device that broadcasts UDP packets to all computers, and a kitchen display system that likewise broadcasts UDP. They may also have incoming TCP packets for our custom online ordering module. Do these TCP/UDP connections count toward the inbound connection limit? I'm aware that Windows 7 has increased the limit to 20 but we might have future customers that will push that limit. Thanks in advance

• Do there exist programming languages where a variable can truly know its own name?

  - by Job

  In PHP and Python one can iterate over the local variables and, if there is only once choice where the value matches, you could say that you know what the variable's name is, but this does not always work. Machine code does not have variable names. C compiles to assembly and does not have any native reflection capabilities, so it would not know it's name. (Edit: per Anton's answer the pre-processor can know the variable's name). Do there exist programming languages where a variable would know it's name? It gets tricky if you do something like b = a and b does not become a copy of a but a reference to the same place. EDIT: Why in the world would you want this? I can think of one example: error checking that can survive automatic refactoring. Consider this C# snippet: private void CheckEnumStr(string paramName, string paramValue) { if (paramName != "pony" && paramName != "horse") { string exceptionMessage = String.Format( "Unexpected value '{0}' of the parameter named '{1}'.", paramValue, paramName); throw new ArgumentException(exceptionMessage); } } ... CheckEnumStr("a", a); // Var 'a' does not know its name - this will not survive naive auto-refactoring There are other libraries provided by Microsoft and others that allow to check for errors (sorry the names have escaped me). I have seen one library which with the help of closures/lambdas can accomplish error checking that can survive refactoring, but it does not feel idiomatic. This would be one reason why I might want a language where a variable knows its name.

• Mapped network drive missing from My Computer and Explorer

  - by matt wilkie

  On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G:, if that matters. Other mappings work fine. Other profiles one the same machine have no problem seeing G:. I can access the G: just fine typing it into the address bar or in CMD shell. I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off,on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd.ref We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable. So, anyone have any idea why XP won't show this drive letter? or how to fix it?

• Outlook 2010 + Move IMAP PST file = Outlook data file cannot be accessed

  - by GWB

  I set up a new IMAP account in Outlook 2010. It works but creates IMAP PST file in C:\Users\User\AppData\Local\Microsoft\Outlook. I want the file on my data drive in D:\Users\User\Documents\Outlook Files (the same folder where outlook automatically creates the local Outlook PST. I followed the instructions here to move the IMAP PST. Testing the account (send/receive) works fine, but if I try to manually send an email I get error 0x8004010F Outlook data file cannot be accessed. I've tried repairing the PST using SCANPST (it always finds errors), and deleting and recreating the account but I get the same error. If I move the PST file back, it works again, but this is not ideal. Note: I don't think this is a duplicate of this question as the cause is different and the solution does not help.

• My webcam just came on "out of the blue"

  - by AngryHacker

  I have a Microsoft LifeCam HD sitting atop my monitor. Today, completely out of the blue, its light came on -- I was simply browsing the web (in Chrome) when it happened. After about 5 minutes the webcam turned off. Naturally, I immediately suspected my ex-wife (when in doubt, I always suspect her), but she isn't computer savvy enough. I looked over the process list and didn't see anything suspicious. I am running a couple of open source projects and free apps (e.g., greenshot, powermenu, supertray), but I've had them for years. Autoruns reports nothing suspicious in the startup and neither does Windows Defender. Anyways, what could it be? What should I look at next?

• How to modify existing keyboard layout (RU, kbdru.dll)?

  - by Anton

  There's a program I'm thinking of using called Punto Switcher that detects a language I'm typing in and switching entire word between Russian and English. The problem I have with this setup is that even though most of Russian letters "correspond" to English letters, Russian keys are scattered all over the keyboard and I don't feel like learning them all as I type in English mostly. Now, the program is very specific about me using RU, kbdru.dll file, not any other and if I use a custom keyboard under Russian, it doesn't recognize what I type so I think I should change the default RU keyboard. I created my custom keyboard using Microsoft's tool and I need to modify original one. I think it will take more than just replacing a file. Help?

• Windows 7 Desktop background picture in Group Policy displaying black - XP working correctly

  - by Shawn Gradwell

  We want everyone on the Windows Domain to have the same desktop background. This is set up in a Group Policy. This works great in Windows XP but the Windows 7 machines display a black background. I have re-created the Group Policy, done various tests with different types and sizes of files Enabling and Disabling Active Desktop. I have researched and tried some options and patches from Microsoft as well. Any idea what I can try or even how to determine the problem?

• Windows 7 root certificate updates

  - by hstr

  I work for a company that uses Windows 7 for end user computing. The Windows 7 computers are updated via a WSUS installation, and access to Microsoft Update is blocked. We have a problem with a number of websites, who's certificates appears to be invalid, though they are perfectly ok. The problem is, that Windows 7 apparently does an on-demand update of root certificates through Windows Update, rather than rolling out a monthly update, as with Windows XP. Now that Windows Update is blocked, how should root certificates be updated? It appears that WSUS is not handling this feature. Thanks in advance.

• Can't rename folders in Window 7/32bit after anti-virus change

  - by Tasos

  I recently started having the common, as I realized, problem of not being able to rename folders in Windows 7 (32 bit). I don't understand why it happened after almost a year of ideal use of Windows 7. I haven't removed the libraries nor can I think of anything else that could potentially cause this, at least as far as I know. The only thing I did recently was to change my anti-virus program from the freeware version of Avira to the freeware anti-virus Microsoft Security Essentials. Any idea on what the problem is and how to fix this?

• SQL Server 2005/2008 Licensing Decision

  - by Hakim

  Hello, I have purchased a dedicated server from a reputable Hosting company. They only have Windows Server 2008 OS installed on it and NO Sql server. Server Configuration is Intel Dual core Processor with 2GB of RAM and 100GB HDD. I wanted to host my web services on that server which will be using the MS SQL Server 2005 at the backend.There are multiple web services and each using a different Database. Microsoft has CAL basis Licensing , Which I understand is based on number of users accessing the database directly ( I may be wrong ) . But my users will be accessing the webservice and no direct connection to the database as such. Yes but the number of users accessing the web server cannot be known and is not under my control. Which Licensing is best suited for this kind of setup ? I don't need analysing and BI services right now ,but i may want to upgrade that in future may be. Any help will be appreciated. Thanks

• copy list of video file names to text file along with their runtime?

  - by Adam Johnston

  Copy list of file names to text file? I am linking the above page because of its relevance to my question. Is there anything similar that can be done to output a 'plain' looking text file (or xml or csv file) with basically the same data that the following cmd prompt produces: dir > c:\list.txt However only difference I need is the runtime of any and all video files included in the outputted file. Can this easily be done? Please let me know whether this can be done in the python terminal as well since I am familiar with that was well as Microsoft's dos prompt. Thank you so very much.

• Was Windows 95 an Operating System?

  - by shantnu

  This question maybe a bit historical, but we didn't have Superuser at the time. Around 2000 when I was starting my Computer science degree, a subject was Operating systems. The teacher asked us to list a few OS. I said Windows 95. I was immediately shot down. Windows 95 wasn't on OS, as it used DOS to boot up. The actual OS was DOS, Win 95 was just a graphical wrapper around it. I pointed that all trade magazines called Win95 an OS, but was told that they were run by laymen, and as a professional, I should know better. DOS was the only OS from Microsoft, at least till Win2K came out later that year. So 12 years on, I'm still not sure. Could Win 95 be considered an OS?

• How to enable winhlp on Windows7 64bit?

  - by BGM

  Salvete! I just discovered that winhlp32.exe won't run on Windows7 64bit. I can't run the application, and I can't run hlp files either (but .chm files run fine). How do I make this work? I have downloaded the Microsoft fix here and restarted my computer, but to no avail. I can see the file winhlp32.exe in my c:\windows directory, but cannot run it. When I do run it, I get Windows' own "Help and Support" entitled, "Why can't I get Help from this program?" which sends me to the link above! How can I make it work?

• Community TFS Build Manager available for Visual Studio 2012 RC

  - by Jakob Ehn

  I finally got around to push out a version of the Community TFS Build Manager that is compatible with Visual Studio 2012 RC. Unfortunately I had to do this as a separate extension, it references different versions of the TFS assemblies and also some properties and methods that the 2010 version uses are now obsolete in the TFS 2012 API. To download it, just open the Extension Manager, select Online and search for TFS Build:   You can also download it from this link: http://visualstudiogallery.msdn.microsoft.com/cfdb84b4-285e-4eeb-9fa9-dad9bfe2cd10 The functionality is identical to the 2010 version, the only difference is that you can’t start it from the Team Explorer Builds node (since the TE has been completely rewritten and the extension API’s are not yet published). So, to start it you must use the Tools menu: We will continue shipping updates to both versions in the future, as long as it functionality that is compatible with both TFS 2010 and TFS 2012. You might also note that the color scheme used for the build manager doesn’t look as good with the VS2012 theme….   Hope you will enjoy the tool in Visual Studio 2012 as well. I want to thank all the people who have downloaded and used the 2010 version! For feedback, feature requests, bug reports please post this to the CodePlex site: http://tfsbuildextensions.codeplex.com

• How can I set an arbitrary (non default) attribute for an AD user or AD Contact?

  - by makerofthings7

  I have AD Users, or contacts that are not Exchange Mailbox users, or contacts. I also have a SSO system (Ping Identity... technology similar to Microsoft ADFS), where it leverages the AD Schema attribute: CustomAttribute1 to store information needed for SSO. This CustomAttribute1 was created by the Exchange Schema. I would like to use CustomAttribute1 for both AD Users and AD Contacts, as well as the Exchange equivalent user and contacts. Question Since the Exchange tools will only allow me to modify "Exchange" users, what is the way to modify the AD counterpart? e.g. if the following command sets a mailbox... set-mailbox -Identity [email protected] -CustomAttribute1 [email protected] -WarningAction silentlyContinue What command will allow me to update an AD user (non-mailbox) under the same schema attribute?

• RDP windows key jamming

  - by VBwhatnow

  There is a known bug in RDP; if you lock the screen while connected to a computer the computer you are connected to will have its windows key jammed. There are a few work arounds that involve hammering the windows key and re-locking the screen but this isn't a bug I want to put up with anymore. Microsoft has said they wont fix this bug because it's XP specific and they are only working on security bugs now because XP is at end of life. Is there any way I can fix this or am I just going to have to find an alternative remote desktop software.

• Windows 7 Keyboard Repeat Rate and Delay are Reset on Resume from Standby / Sleep

  - by Synetech inc.

  I always keep my keyboard repeat rate at the maximum and the delay at the minimum for optimal keyboard responsiveness. Under Windows 7 however, I have found that the rate and delay are reset to the defaults (ie the one’s that are set with a fresh Windows installation) whenever the system resumes from sleep and requires opening the keyboard control panel applet (which already shows the desired settings) and manually setting them again by pressing Enter. I have seen a couple of posts in the Microsoft support forums, but no solutions. Does anyone know of a way to fix this?

• Mouse will not click and drag

  - by C. Ross

  My mouse is currently having trouble with Click and Drag. It moves well, it clicks well (including double click); but it will not click and drag correctly. When dragging it just drops the highlighted area almost immediately after starting it. The operating system is Windows 7 x6, and the mouse is a Microsoft 5 Button laser wired model that's approximately 3 years old. The problem is relatively new, but has been happening consistently for several weeks through several reboots. Is there anything to try besides buying a new mouse?

• How (much) is virtualization used today?

  - by BLAKE

  I know that where I have worked, I have pushed alot for virtualizing our servers. I think that it is much easier to implement and maintain than physical servers. I have been using Microsoft's Virtual Server 2005 R2 since it was released. Right now at my workplace we have 12 VMHosts that hold about 55 VMs. We have 6 other servers that we have been unable to convert to VMs. I want to know how other people in our field view virtualization. I know that I have had developers dislike the notion of VMs claiming major performance hits. What do other Sys Admins think about virtualized servers?

• What do I put on my developers box in regard to SharePoint 2010

  - by Jisaak

  So we are venturing out into the world of SharePoint and it seems that I have to install SharePoint Server directly on each developer's box. Is this correct? I have SharePoint up and running on a separate sever so it seems redundant to have to install it on each box. Not to mention installing SharePoint on Windows 7 is a pain in the ars. I'm just trying to clarify how to correctly set the environment up. I've been using this link as a guide so far: http://msdn.microsoft.com/en-us/library/ee554869(office.14).aspx Any advice is greatly appreciated!

• Sharing RAM resources between 2 or more computers

  - by davee44

  I know there was a somewhat similar question before: How to share CPU or RAM? But, let me just specify it a little more... When Microsoft Windows requires more RAM capacity than available it uses a swap-file to temporarily store the data there, this is actually something like a hard-drive-based RAM. This technology is used for many years. Theoretically, it shouldn't be too hard to implement a similar technology that uses the RAM of different computer(s) in the network for temporary data storage. This just requires a software that runs on computers in the network that accepts and returns data from/to the main computer and keep that data in the RAM; plus the operation system of the main computer must have the ability to use computers in the network instead of (or in addition to) the swap-file. I wonder, are there any implementations of this idea? This would allow users to build RAM clusters using all of their home or office computers, that will boost the performance of a single computer for some development/gaming/video tasks, etc.
