Hi, I look after two sites connected by a leased line. There is an NT4 PDC and BDC at site A and just an NT4 BDC at site B. I have just promoted the BDC at site A to become the PDC for our domain. However now the BDC at Site B cannot find the PDC. Similarly although the site B BDC does appear in server manager on the PDC, I am unable to access it and get an error message that 'the network path was not found'. Is it just a case of restarting all the servers. Thanks in advance, Christian Waller

It sounds to me that your network has lost knowledge of the Browser List, and an election must be forced in order to reassign who has what roles. The following quote comes from Microsoft web site: http://www.microsoft.com/technet/treeview/default.asp?url=/TechNet/prodtechnol/winntas/support/chptr3.asp This shows how to change the new PDC and to force the election: Another parameter in the registry, IsDomainMasterBrowser, helps to determine which servers become master browsers and backup browsers The registry path for this parameter is as shown below. \HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \Browser \Parameters Setting the IsDomainMasterBrowser parameter entry to True or Yes on a computer makes that computer a preferred master browser. A preferred master browser has priority over other computers in master browser elections. Whenever a preferred master browser starts, it forces a browser election. Any computer running Windows NT Workstation or Windows NT Server can be configured as a preferred master browser. When the Browser service is started on the preferred master-browser computer, the Browser service forces an election. Preferred master browsers are given priority in elections, which means that if no other condition prevents it, the preferred master browser will always win the election. This gives an administrator the ability to configure a specific computer as the master browser. To specify a computer as the preferred master browser, set the parameter entry for IsDomainMasterBrowser to True or Yes. Set the parameter in the following registry path: \HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \Browser \Parameters Unless the computer is configured as the preferred master browser, the parameter entry will always be False or No. There is no user interface for making these changes; the registry must be modified. What I read from this is to change the registry's 'Parameter' setting on the new PDC and reboot it, which will force a new election. Everything should be fine after that.

Force an election by restarting the netlogon service.
