Hi Denise,

thanks for your reply.

The domain we are on is 'Portsmouth' and the user is 'OP5IXPR' - this is both for our Windows session and our PPWatch service.

Thing is, as I said in the previous post, the Works Orders process worked fine either side of the 09:33 failure. I notice in the error log it says:

A TimeOut has occurred while trying to logon.
Could it simply be a case of too much traffic or something that caused the timeout?
