On your hard shutdown, did you also unplug the power from the pc, and let it sit for a few moments to drain the power out and plug it back in?

Thought I would tap the great knowledge base here. This may not be Enterasys specific although the environment is C3's.. I've seen several times where a pc (Dell 970/980) will lose network connectivity after it has been working. This usually happens after a power down and up cycle. When the user starts for the day. The initial reported problem begins with no DHCP request from the pc. Further investigation of the C3 stack port shows no incrementing inbound counters on the user port. Port status shows ok at 1G. Mirroring the port shows no inbound packets. Outbound counters do increment. Hard coded ip address on the pc presents no packets either. Another pc plugged into that port responds correctly. Tried hard power on the pc to no avail and changed out the patch cable from pc to wall jack. Strangely if we move the pc to another network----several minutes away at the help desk --- it works. Returning the pc to the original port it works!!!! Any ideas where to look next or things to try would be greatly appreciated . Really wierd! thanks in advance Walt Witkowski Primary Network Specialist - Office of Information Technology - Delaware County Community College ellucianTM 610-359-5017(phone) / 610-359-4123 (fax) / 856-217-4430(cell) [email protected]<mailto:[email protected]> [email protected]<mailto:[email protected]> www.ellucian.com<http://www.ellucian.com/> * --To unsubscribe from enterasys, send email to [email protected]<mailto:[email protected]> with the body: unsubscribe enterasys [email protected]<mailto:[email protected]> NOTICE: The Arkansas Department of Human Services has determined that this message may contain confidential or otherwise protected information.
