Just [user] doesn’t cut it!
I was installing a MOSS system yesterday, and starting the WSS search service was causing me problems. I kept getting errors of the form
SearchServiceInstance.Provision (server ‘VM-AWB-MOSS01’) failed. Setting back to previous status ‘Disabled’.
Well, a google trawl turned up a fairly obvious solution – which just didn’t occur to me. Make sure the account name includes the domain!
