WCF Windows Service (again!) - Service account

Question

Hi all,

You must be getting fairly sick of me by now! But anyway:

I've deployed my service and its working fine. Its currently deployed under the 'Local System' account. However, I now need to change this to work under a speciific user account, but when I build my service with that account set, the Opening of the Service Host just sits and doesn't appear to return. This also happens with other service account settings, i.e. Local Service.

The reason I know its not returning is my code outputs to a text file either side of the call to myServiceHost.Open(). When in 'Local System' I get 2 lines written to the text file, when in 'User account' I only get the first line.

Anybody got any ideas? Either to resolve the issue, or where to start debugging?

Cheers,
Greg
