Configuring firewall port exceptions for Windows XP SP2 and Dell OpenManager IT Assistant

I've scanned this forum and I'm having trouble determining the port exceptions I have to make in the Windows XP SP2 firewall to allow systems to be detected by OpenManager IT Assistant.
 
I've found the Port Usage page of the Dell OpenManage IT Assistant Reference Guide, and accordingly have the following ports open via group policy:
 
161 (UDP)
162 (UDP)
2606 (UDP & TCP)
2607 (UDP & TCP)
11487 (TCP)
11489 (TCP)
 
With these ports open, IT Assistant cannot detect my Dell Optiplexes with OMCI.  My Windows 2000 systems are detected with no problem.
 
The problem may be that the firewall is blocking the dynamic ports greater than 32780, but I don't know the syntax for opening this range via group policy.
 
Can anyone assist me with a simple list of ports and how to open them via group policy?  We need to inventory systems in anticipation of replacement and are also eager to use SMART detection as reported through IT assistance to warn us of imminent hard disk failure in our older systems.
 
TIA for your help.

I am also having issues with OMCI and Windows XP SP2.  I have turned off the client firewall and IT Assistant does not recognize the systems with SP2.  I tried Tech Support today, but they said they do not support this.  I was going to try again tomorrow unless someone out there can help.

Thanks.

You might try running netstat while the discovery process is active.  There may be other ports needed that XP firewall is blocking. 
 
Try this at a command promt on the IT asst server:
 
netstat -an 1
 
do a force discovery of the the XP box then check the netstat output for syn sent associated with the destination IP.
 
If you are seeing the Win2K boxes and not the XP boxes, I would bet that the problem is with the firewall on the XP box or another firewall between the ITA and XP boxes.

I hope the fix this soon!

Dell is shipping their Windows XP boxes with SP2...and no way to remove it.

Answering my own question....

Wasn't a firewall issue that was preventing detection of my Optiplex systems after they had been upgraded to Windows XP SP2.

I uninstalled IT Assistant and reinstalled with the option to do CIM discovery.  After rebooting and rediscovering, systems are now properly populating the inventory - and just in the nick of time, as I need a reliable inventory in contemplation of replacing older units.

Apparently the move to SP2 necessitated CIM discovery for the process to work.  Got an inkling of this when I "read the (friendly) manual" (the posting software prohibits the acronym....)
