PS 2 mouse affects network access

This is a tricky question, I am not sure that it is network or hardware related. While rebuiling a W2K Pro, SP4 with all the patches etc, workstation. I had a serial mouse plugged into the system. The network, has been setup up successfully. I can see the domain, access all mapped drives, connect to the internet etc. The problem that I have is that when I connect a PS2 mouse to the system, I cannot access the network at all. Mapped drives are not accessable, the network shares are unavailable etc. I have uninstalled the PS2 mouse and network card completely and reinstalled both items. If I remove the PS2 mouse and reboot the network is fully active. The problem still persists. The are no conflicts on the system dialog box for both mouse and network card. What could I look at besides rebuilding the system totally.

You looked for an IRQ conflict and didn't see any? In Device Manager?

Hi iamgod, I have just tried your solution by uninstalling the mouse under safe mode. This did not solve the problem.
Thank you

Hi there again.
Iamgod ignore the previous email.
Your suggestion has worked. I was a bit hasty on the previous call.
I think the problem originated when I built the system with a Serial mouse and Windows got a bit confused.

Thanks to pseudocyber for responding as well.
