Weird error due to permissions
So it is 1:30 am and I am sitting here trying to hodge-podge a medium server farm together to test a Kerberos issue/theory. My environment is a Windows Server 2008 box as my central admin, WFE, Excel, and query server (physical hardware), Windows Server 2003 VPC as the Index server, and a another VPC (running on another host) playing the role of SQL Server 2005 and Domain Controller. Does it sound like fun? Yeah right.
Anyway, I started getting the error below whenever I tried to start the Office SharePoint Server Search service on the index box.
An unhandled exception occurred in the user interface.Exception Information: Unable to generate a temporary class (result=1).
error CS2001: Source file 'C:\Windows\TEMP\xm7qyq1x.0.cs' could not be found
error CS2008: No inputs specified
Quick search? Nothing. A little playing and guessing and the issue turned out to be permissions. For some reason WSS_Admin_WPG and WSS_WPG did not have the any rights to c:\windows\temp on the central admin server. So I gave wss_admin_wpg full control and wss_wpg read & execute. Fixed everything instantly. I am guessing this is an issue with my random servers (not clean installs for this test) and not a W2K8 issue. Anyway, hopefully the error message and fix saves someone else some time.
