I have a strange one, periodically I cannot log into the Workgroup vault and get the yellow caution symbol alongside the connect button. When this happens I assume that the network is down but I can ping the server, get email and go online (web). Most of the time after about 10 minutes I can simply log in and all is fine. Our IT is stumped as well, it happens a few times a week. Anyone got any ideas that I could look into?
Thanks for your help.
