Assembly system.data.dll security permission grant set is incompatible between appdomains.

[Brian Takita]

Hello,

I'm getting the following error at the end of this message when trying
to run the ReportManager and the ReportServer:
Assembly system.data.dll security permission grant set is incompatible
between appdomains.

I had to apply KB 887787 (http://support.microsoft.com/?kbid=887787) to
fix my previous error, which stated...
Assembly microsoft.web.validatepathmodule.dll security permission grant
set is incompatible between appdomains.

This is running on a Windows 2003 SBS.
I recently installed a bunch of windows updates and security patches.

I could not find anything relating to the System.Data.dll security
permissions.

Thank you,
Brian Takita
