We had MCP's scratching their heads over an up and down network at our company. The main symptom I could always detect was a screwy master browser, with lots of messages in the event log of the PDC about elections failing etc. An MCP friend of mine finally swapped out the hub (we were using broadcast, not switched) closest to the PDC and the trouble all stopped. I would check over your hardware again. Tom Turak -----Original Message----- From: Shawn M. Shea [mailto:[log in to unmask]] Sent: Wednesday, August 09, 2000 10:59 AM We have two NT servers arranged as PDC and BDC and constantly get errors regarding the election for a master browser. Server3 (the BDC) keeps receiving the error that it cannot contact Server2 (the PDC) to complete the election process. This seems to be creating excess traffic and when the BDC is connected to the network all network traffic is slowed to a crawl and we are not able to access the internet (DSL) through the PDC. In running network monitor there is no other traffic on the BDC. We have done the registry edit to disable the BDC trying to become a master but it still causes problems. Has anyone experienced this? Thanks for any help. Shawn M. Shea Microsoft Certified Professional [log in to unmask] Curious about the people moderating your messages? Visit our staff web site: http://nospin.com/pc/staff.html
