I must agree, this has been a subject of discussion. I did see some event logs which referred to the NIC, I downloaded the latest drivers ad have installed them. Due to the time between problems this has not been conclusive. The trouble with it happening over the weekend mostly it has been difficult to identify log errors that apply to this issue. I have other tasks to comply to from other answers to this issue which I will carry out next week and reply when I have some results. Many thanks for the response so far. To date it has not been a problem. Let's wait till Monday!!! DAVE -----Original Message----- From: Bruce J.

Due to other issues all but 5 users are on 1 server (approx 450 but only approx 150 active) 2nd server has the other 5 users. The 3rd acts as an archieve for all emails. Approx once every 2 weeks users see "Outlook is requesting Data". Processors are normal, nothing being reported in the logs but a reboot of the main server sorts the problem. Upto this last 2 weeks, if this occured it was mostly on a Monday but this last 2 weeks it has happened on a Tuesday and today (Thursday). Any thoughts.
