On one of my Win2k member servers I keep getting the message DCOM was unable to communicate with the computer XYZ using any of the configured protocols. This is causing the system log to fill up very quickly. 3 computers are generating this error. The funny thing is one of the machines generating the error isn't even on the network. What is causing this and how do I resolve it?

It is likely you don't need dcom, so just disable it. you do that by starting dcomcnfg, then selecting the default properties tab and then just uncheck "enable distributed computing on this computer". Otherwise, if you need dcom you can correct the settings in that applet.

If you the error in event log appears something like the following:

EventID:10009
Source:DCOM
Type:Error
Description:DCOM was unable to communicate with the computer Remote Server Name using any of the configured protocols

Then try this:

Bring up the Component Services Administrative tool. On the Start menu, point to Programs, Administrative Tools, and then click Component Services.
In the console tree of the Component Services Administrative tool, right-click the computer on which you want to configure the protocol, to bring up the context menu.
Click the Properties menu to bring up Computer Properties dialog box.
Click the Default Protocols tab.
If you have any of the Datagram protocols (UDP/IP or IPX) protocols listed here, click to select, and then click Remove.
If you do not have any of the connection-oriented protocols in the list, click Add to bring up Select DCOM protocol and endpoint dialog box.
Choose Connection-oriented TCP/IP Protocol as the protocol sequence, and then click OK.
Add any or all of the connection-oriented protocols to the default protocols this way.
Move Connection-oriented TCP/IP Protocol to the top of the list.
Restart the computer for the changes to take effect.
