Hi Everyone,

I got the dreaded "Server Unavaliable" error message again this morning when
hitting our new portal. This has happened about 5 / 10 mornings since
launch. There is NO CRITICAL error in the event log which makes this almost
impossible to debug. A quick IISRESET fixes the problem but that is clearly
not the solution as all our early bird users have no portal when they get
in...

Our staging environment has never once done this. Somebody mentioned they
get the same error and have set their services to Auto Restart in service
manager. What service(s) should I set to auto restart? All the IIS related
services or just IISADMIN?

Any help would be greatly appreciated.
