Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I am using VSTS 2008 + C# + .Net 3.5 + IIS 6.0 + Windows Server 2003 Enterprise x64 SP2 + ASP.Net. I am using anynomous authentication + Windows authentication mode in IIS web site, and I map the user identity to mycorp\george in anynomous account and also use mycorp/george to run IIS worker process. I have also added mycorp\george to administrator group of the IIS web server machine. "mycorp" is the (Windows Active Directory) domain name my department is using.

I always got unauthorized error (401) when accessing the web site from another computer using account mycorp\george (but no error when accessing web site from local computer to access web site.) The web site is a share point web site using Share Point Service 3.0.

I have also used IIS authentication and authorization tool to do diagnoistics, here is the tool I am using http://www.microsoft.com/downloads/details.aspx?familyid=63AAF167-2138-4231-B6ED-56298044BD3B&displaylang=en

This tool reports similar authentication and authorization issue,

mycorp\george account does not have Access this computer from the network privilege Path:W3SVC/1670937635/ROOT AuthType:Anonymous Server's response: HTTP/1.1 401 Access denied Learn about IIS status codes Path:W3SVC/1670937635/ROOT AuthType:Anonymous

Any ideas what is wrong? I think for administrator account like mycorp\george, the account should have no privilege (authentication and authorization) limitation issues.

Thanks in advance,

Hi splattne, any ideas to analyze further? Are there any settings to prevent administrator from remote access? –  George2 Sep 21 '09 at 8:51
I have used process monitor to monitor all the information of log when submit request to the web server, I suspect this one is the root cause, because it is the only permission error (other errors are path not found, end of file and buffer overflow, which I do not think it is a permission issue, another reason is wsstracing.exe seems to be a Windows Share Point component) "41:54.8 wsstracing.exe 3364 WriteFile C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\TestServer-20090921-2118.log FAST IO DISALLOWED" Any ideas what is wrong? –  George2 Sep 21 '09 at 13:52
