BUG: Error When You Invoke Methods on a Web Service by Using ASP (322886)
The information in this article applies to:
- Microsoft Web Services (included with the .NET Framework) 1.0
- Microsoft Internet Information Server 4.0
- Microsoft Internet Information Server 5.0
This article was previously published under Q322886 We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site: SYMPTOMS When you invoke methods on a Web service, you may receive
the following error message:
System.InvalidOperationException: Unable to generate a temporary class
(result=1). error CS2001: Source file 'C:\WINNT\TEMP\gggcyckb.0.cs' could not
be found error CS2008: No inputs specified at

CAUSE ASP.NET Web Services sometimes use the system Temp folder
when they process WebMethods. If the thread that is processing the request uses
an Identity that does not have read/write access to that folder, you receive
the error message. RESOLUTION To avoid this problem, give read/write priviledges for the
Temp folder to the ASPNET account. When ASP.NET Web Services process
WebMethods, the identity that is used most frequently to gain access to the
system Temp folder is the local ASPNET account, which is the default account
under which ASP.NET applications run.
However, if you have
configured your application to use impersonation in its Web.config file, the
thread can also use the identity of any caller. If this is the case, all
potential calling identities must have read/write priviledges to the Temp
folder. A likely calling identity is the Internet Information Services (IIS)
application's anonymous account (typically the
ISUR_xxx account). The thread may also use the
IWAM_xxx account. STATUSMicrosoft
has confirmed that this is a problem in the Microsoft products that are listed
at the beginning of this article.
