I have a small 192.168.0.x network I am upgrading, so I built a Server2003 DC 
and created a new AD domain to move into (I have the luxury of being able to 
move a few computers at a time)  Currently I have:

Server2003 DC
Server2000 Exchange server [Exchange2K]
(3) XP Pro workstations 

All software is in the most current service pack.

One of the XP machines is always available when browsing the domain.  The other 
two machines appear in the network when they are re-booted, but disappear from 
the browser list after about 15-30 minutes.  I have looked and looked to see 
how the one computer differs from the other two, but have had no luck.  Here is 
a partial list of what I have tried:

- Made sure "Enable NetBIOS over TCP/IP" is checked in TCP/IP properties.
- Added the DC as the WINS server
- Removed the DC as the WINS server
- Changed from DHCP to static I/P's
- Windows firewall is turned off
- Turned on and off virus protection software (though it is ON on the one 
working XP machine)
- Used "net config server /autodisconnect:xx" to turn off autodisconnect (-1), 
or to set it really long (65,000 minutes). Default is 15 minutes.
- Turned off the DC
- Turned off the Exchange Server
- Rebooted these 2 machines in various permutations
- Used the NetBIOS Browsing Console, which tells me "System Missing from its 
Local Subnet Master Browser's List"
- The W/S's are not hidden
- The W/S's do not have server comments over 48 char (in fact, none at all)
- The browser service is running and set to automatic
- Pulling my hair

Throughout all of this, you can still access resources on the 2 vanishing 
computers via drive mapping, UNC pathing, etc.  They just disappear from the 
browser list.

Any and all suggestions are welcome, and thanks in advance!
