I'm checking with a few folks internally to see if they've seen this before. In the meantime, I'd go ahead and open a ticket with support.
Can you try this....
“Add” >“New Device” from the Devices tab and provide the ip Address, Credentials etc. It will tell you that found “Existing Device”. Click on “Re-Scan Device” This almost always corrects this issue.
Thanks for the reply. We are running v8.5 at the moment. The upgrade to 9 isn't scheduled for this year.
Use the iReasoning MIB Browser from the IPM machine to walk an OID on the target computer.
In the address field, put the ip or fqdn of the machine.
Click advanced and enter the community string
In the OID field type .0
In the operation click Get Next
If you can not walk the tree, IPM will not be able to walk it either.
If that fails, you may want to use wireshark on the source and target machines to find out what is happening to the packets.
