IT Assistant Discovery issues

Question

I am having some problems ITA connectivity.  I have all systems correctly configured with snmp read-write community strings and the ITA server ip address is listed as a trap destination.  I have Server Admin installed on all the systems to be discovered.  I also have the community strings setup on the server side. When I force a discovery each of the systems are discovered individually however, when I discover all of the systems at once they seem to cancel each other out.  In other words, when one system is discovered the previous system is deleted.  The funny thing is that this only happens with about half of the systems that I try to discover.  Total count is about 40 systems all running win2000. Any suggestions or ideas would be greatly appreciated. Things I've done so far.Checked all community strings, server side and client side.Completely formatted the ITA server and reinstalled Win server2003 and ITA.Uninstalled and reinstalled Server Admin on the client side.Checked to make sure I didn't have duplicate SID's. Thanks!

This could happen if the names or the IP addresses of the systems are duplicated. The most common case is when you have systems in a cluster. IT Assistant will sometimes see the two clustered systems as the same system and only list one.

There are also times when the lab/testing environment uses the exact same subnet as the production environment. Since the two computers have the same IP address, IT Assistant deletes the first one.

Thanks for the information. I found out that the problem existed with duplicate MAC addresses which were created on all of our VMware servers.

The fix was to add the duplicate MAC addresses to DUPLICATE_NAME_EXCLUDE_LIST in the dconfig.ini file.

Thanks again,
