I have installed OME on an Windows Server 2008.
Installation went fine. SQL Express 2k8.
When Iaunch the Essential Icon I get an Http Error 500.19 Internal Server Error.
I checked the permissions in IIS and on NTFS. Think this should work fine.
I've createt an index.htm in C:\Program Files (x86)\Dell\SysMgt\Essentials\WWWRoot\Essentials\ but i can't open it. Same Stange 500.19 Error.
The Server has an WSUS already installed. OME runs on port 2670 (don't know if that changes anything).
I am running out of ideas...
I come across the same problem as yours, also installed to a WSUS 2008 SP2 server, could you please pin-point how you slove your problem .. Many Thanks for your help in advance ... !!
