Virus Chest RPC server error

I know this is the 100th time you are seeing this and I’ve read through a number of emails pertaining to this but none seem to work…

In my test network I have a Windows Workgroup that consists of 2 XP PRO PCs and one XP Media Center edition. (basically pro)

I have ADNM installed on one XP PRO machine and have deployed netclient to all three machines (one that ADNM is on and the 2 others.)

XP SP2 is on all machines.

With XP SP2 firewall turned on on the media center PC, I CANNOT connect to virus chest. I get an RPC server is unavailable error. If I turn off the firewall it works fine.

When the firewall is turned on, I have gone in and put a check mark in the boxes for File and printer sharing, and remote Desktop. I have added TCP ports for 16111 and 16108. I have even uninstalled and reinstalled netclient on that machine. If the firewall is on, it won’t work.

On the other hand, I have the other XP PRO machine that doesn’t matter WHAT I do to the firewall, I can still access the chest. I have gone in and unchecked everything (File and printer sharing and remote desktop). I have not extra ports open and the firewall on. On that machine I STILL have no problem accessing the chest.

WHY??? and what else can I try on the media center PC?

I checked this out here because I have a similar problem on my larger DOMAIN based network with 65 PCs. I have a machine or 2 with the same scenario.

The remote chest needs port 135 (RPC) open too.
Remote desktop is not needed, File and printer sharing is needed only for remote deployment.

Geesh… Thanks I meant remote administration which appears once you join a domin. In addition, I found TCP port 16108 necessary to be open to get through the firewall.
