Problem with IIS and IMAP

[tmod]

Hi

Recently we have been having a few problems with IIS and IMAP on one of our Exchange 2003 servers. Every so often (not at regular intervals) our OWA site stops and the IMAP service stops. These can both just be restarted and then everything carries on working for awhile. Has anyone seen this problem before and know how to solve it?

Thanks

Any error in the eventlog?

Nothing that I think is overly relevant, the only thing in there is a perflib error in the application log relating to the .net framework.
