Which protocols are used depends on what the needs of the traffic are. Windows 2000 uses TCP/IP as its default protocol -- unlike NT 4, NetBEUI is no longer installed. NetBIOS -- over TCP/IP -- is used when two machines are doing file and print sharing. SMB (Server Message Block), the file/print sharing application protocol, requires NetBIOS, which in turn runs over TCP/IP. Unlike what you may have heard, typically you can't expunge NetBIOS from your network. If you're not using any services that require SMB, *and* you're not running Windows 2000 Advanced Server clusters, it's *possible* to turn off the TCP/IP-NetBIOS helper and shut down the server service, which would eliminate NetBIOS. And yes, you can have trusts between Windows 2000 and NT 4 domains. Your Windows 2000 domains can even run in native mode. The only time you need to keep your Windows 2000 domains in compatibility mode (actually called "mixed mode") is if you have to keep some NT 4 BDCs in the same domain. ___________________________________________________________ Steve Riley Microsoft Telecommunications Consulting in Denver, Colorado [EMAIL PROTECTED] +1 303 521-4129 or [EMAIL PROTECTED] www.microsoft.com/isn/ Applying computer technology is simply finding the right wrench to pound in the correct screw. -----Original Message----- From: Paul Gracy [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 5, 2000 11:55 AM To: [EMAIL PROTECTED]; 'netcomm' Subject: RE: Win2K Adding an NT 4.0 box requires that the Win2K machine run NetBT, aka NetBIOS over TCP/IP. It does not require the horrid, evil, 1980's based NetBEUI. This is called 'compatibility mode'. -----Original Message----- From: netcomm [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 29, 2000 6:11 AM To: [EMAIL PROTECTED] Subject: Win2K Hi just started working on Win2k. I have install one win2k domain controller and wish to include one more win2k machine in that domain. ( like a member server concept in earlier version). Now my concern is what would be the protocol for the traffic between these win2k macines. I hope it is not netbios??? Is it possible to have a one way trust relation ship between win2k domain controller and WinNT4.0 domain controller.?? any info or pointers are welcome....
