slow preparing network connections

[Guest okocimski@gmail.com]

I recently deployed an exchange server at a school that I do IT

support for, and all was going well.

 

Just last week, It started to slow down in regards to shutting down

and starting up. When the Ethernet cable is plugged in, it sits there

in excess of 20 mins, at which point I restart the machine manually by

holding the button in. When the Ethernet cable is unplugged during

startup, the machine will load instantly, and log into a cached

profile. When the Ethernet cable is plugged back in after login, all

network services (but not the ones relevant to exchange) are restored.

 

TCP/IP is set manually, with the Prefered DNS being the main DC, and

the Alternate being another DC.

 

I have uninstalled the NIC, and reinstalled it with the latest drivers

for that particular adapter, to no avail.

 

A very strange problem that i cant seem to figure out

 

Please help
