WMI error on servers outside the firewall

[paul]

Hello,

I have some machines (windows 2003 server) outside our firewall that generate the following error if I to the connection test:

Remote WMI test
-----------------------------------------------
\root\cimv2 Remote WMI access test FAILED
Not enough resources are available to complete this operation. (Exception from HRESULT: 0x800706B9)

Remote Registry test using WMI
-----------------------------------------------
\root\default Remote WMI access test FAILED
Not enough resources are available to complete this operation. (Exception from HRESULT: 0x800706B9)

I tried several accounts (including local administrator) but all fail. Some machine are within our windows domain, some are configured for a workgroup.

I have opened all ports in our firewall and configured a static DCOM port.
I hava also applied hotfix KB933061.

Workstations outside our firewall do connect however.

How can I fix this? I would really like to add all of our servers in lansweeper.

Hello,

The problem is solved.

I had to add a port range (5000-5100) instead of a single port.
The strange thing is that a single port does work on a workstation,, but not on a server.

It's not the typical rpc error som it might be firewall unrelated.

This might give a clue : http://support.microsoft.com/kb/246784 (nt4)

Do these machines belong to a domain?

Hello,

I mean a hardware firewall (checkpoint), not the windows firewall. The windows firewall is disabled.

On our hardware firewall I don't see any drops. I see only traffic to port 135, and not on the dynamic dcom port.

I have configured the port according to http://support.microsoft.com/kb/154596

workstations outside the firewall can be managed with the same settings.

Can you review the firewall log to see if any packets are dropped?
