PC looses connectivity to the exchange server

I have a problem with only one PC. It looses connectivity to the Exchange server randomly.

Other PCs are working fine and don't loose connectivity to the exchange server. Error message says: "Connection to the exchagne server has been lost"

start with disabling all 3rd party services on that particular PC and then monitoring it for a while.

My best bet would be the AV on client causing the issue.

When this occurs do you still have network connectivity? Can you ping the server by name and/or ip address?

Did you try disabling all 3rd party services?

That way we can be sure that nothing is interfering with the connectivity.

Please, advice which process should I disabel if any.
BTW. This problem happened again this monring. When I logged in, NIC shows that it is aquiring network address.
Outlook was disconnected from the exchange. Then it showed "Limited connectivity". Next, NIC aquired the IP address. I didn't have to do anything. But, why is it aquiring address all the time. Should I replace the NIC card? I already updated the driver...Please, help

Start -- > 'Run' --- > MSCONFIG ---- > 'Services' tab.

Select 'Hide all Microsoft Services' checkbox.

You can now disable all the rest of the services including the AV.

P.S: Make sure you select the check box 'Hide all microsoft Services' before you disable the services.

Resolved by setting the following with GPEDIT

Computer Configuration\Administrative Templates\System\Logon\

Always wait for the network at computer startup and logon

This way when the user logs in, the network is ready and not "aquiring the network".

Thank you all for your help
