These are some of the easiest cs0016 could not write to output file the directory name is invalid issues to fix!! Right?? Well in most cases ‘Yes'. All you have to usually do is give the Process could not write to output file temporary asp.net files 'access is denied. Account or Impersonating thread identity required NTFS access to the resource.

(EVERYDAY). Most customers would have already Googled for a solution and tried an extensive list of things trying to fix the issue. If they haven't already done that, then they are calling because the WebSite is down and the business impact $$$$$$$$ is "HUGE". In this case the customer was of the former type. He had tried everything to fix the issue but to compiler error message cs0016 could not write to output file - the directory name is invalid no avail. To give you a little background on the issue, the Web Server was a Windows 2003 SP1 server(IIS 6.0) running an ASP.NET WebService. The App used to work fine until it threw the above error. According to the customer, the only way to recover from the problem was to repeatedely reboot the machine and the error would go away. I had never heard of anything like this before. Neither have the 3 Engineers who worked on this issue before engaging me to have a go at the problem heard of anything like this. The typical way to troubleshoot this problem would be to verify that all the permissions and policies were in place as per the knowledge base article Process and request identity in ASP.NET: http://support.microsoft.com/kb/317012 . The AppPool identity was the default "Network Service" account. After verifying kb317012 a dozen times we were still getting the error. The bizzare part was that "Network Service" account had Full Control on "c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files" folder but running Filemon would still show Access Denied for the "Network Service" account on "c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files" folder. The Engineers had tried various way to troubleshoot the

' I have hunted the web to the best of my ability, and have changed the permissions on the Temporary ASP.NET Files fodler to allow the Network Service account full rights, and done the same with the Temp folder. It copies a number of files before failing, so it has write permissions presumably, so I checked the permissions to read from my source folder, and that is working as well. I additionally noted it's crapping out when it tries to to cache the DLL file, and tried turning off my Antivirus protection, as well as turning off UAC, just to see if I could figure out what is blocking this from occurring. I'm fresh out of ideas now. Anybo

I am that desperate who had this error for a while: --- Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS0016: Could not write to output file 'c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\root\4a2d48d3\bcaf750b\bp-we_xs.dll' -- 'The directory name is invalid. ' --- Now the whole story... A long time ago (one month) March 01, 2005 I wrote a message here in this newsgroup asking for help and no one answered because no one seemed to have my problem. The subject of that message was: >HELP!! CS0016 Compilation Error on Windows 2003" Part of the text was: >I have the following problem with ASP.NET running on Windows 2003. My >configuration is: > >1) Windows 2003 Server Standard >2) ASP.NET running in IIS5 Isolation mode (aspnet_wp.exe is alive and >kicking) >3) .NET Framework v1.1.4322 (updated by Windows update) >4) My application running on d:\myapp directory (not c:\Inetpub) My problem was pretty terrible: after some time, or right after an xcopy deployment OVER an existing web site, the aspx pages would never work, throwing the CS0016 error above. Well, dear guys and ladies, excuse my polished way: F**K THE ANTIVIRUS!!! F**K THE ANTIVIRUS!!! F**K THE ANTIVIRUS!!! F**K THE ANTIVIRUS!!! F**K THE ANTIVIRUS!!! F**K THE ANTIVIRUS!!! F**K THE ANTIVIRUS!!! And now that I am very calm and happy, I strongly suggest you few basic rules: 1) DON'T INSTALL ANY ANTIVIRUS ON YOUR SERVER!!! I tried personally NOD32 and Norton Symantec Antivirus Corporate, they just don't work! Nod32 crash the system as soon as you access an ASPX page and the norton bothers iis6 so much that asp pages can't be compiled again! 2) DON'T INSTALL ANY FIREWALL SOFTWARE ON YOUR SERVER!! I didn't have any software firewall installed, but I have been reading lot of bad news! 3) KEEP YOUR SERVER CLEAN!! Don't install any real time file system monitors, or anything similar, Windows 2003 will slow down and crash after some huge load on IIS. The funny thing is that NO ONE have ever had this problem, not even in the web farm where we are renting our servers! They install the Symantec Corporate by default, and I had to uninstall it to check this bug out. If it was me, I would have never installed any antivirus, but I had it pre-installed so I thought "What the hell, it doesn'
