Hi RequestedDeletion,
Have you go any more information on this problem, had a client ring this morning users unable to login to domain server. This server is running as server only, SME 5.6, DHCP server. When I arrived there on the monitor connected to the SME I could not even get a login (same as before) , could only ping the server. Power off and on and all is fine again. Another strange thing, the server is using Tapeware to do the back up each night at 10:00PM, last night (28th May) no back up and on the tapeware "Calendar" it was shaded "grey" which mean skip this day (same as Saturday and Sunday ) BUT the the back up started at 12:01 am on 29th and worked fine.
If no one has an answer then I will have to re-install a lower version say 5.5
Thanks in advance for any advise
John A
