Wmierror Cannot connect to DCOM port 135

[LithiumKid1976]

hi
Just going back to a previous question i logged, where lansweeper was not finding usernames in the search area.
i just got back to check out something, i have noticed that the machines which the user logs on too, are comming up with this error.


Wmierror Cannot connect to DCOM port 135 : Firewalled? (MI3171) 03/06/2009 17:23:03
Wmierror The RPC server is unavailable 0x800706BA (xxxx.marine.ie, MIxxxx, 10.11.2.10) 03/06/2009 17:23:02


and are marked "red" on the digital dashboard (about 38 in total)

so the people who use these machines, we are not getting the full info back.,
How do i go about rectifying this?

Thanks
Damien

I'm pretty sure you already tried it but have you tried stopping the windows firewall service?
Are you able to telnet to any other windows port (445)?

hi
there is a version of that mcafee software that installs a fire wall, but its not on that machine......

Hi,

I'm not sure but I think this has a build in firewall : McAfee Virus and Spyware Protection Service
You can try disabling it as a test.

Thanks

[Hemoco]

Could you post a list of installed software on the client please.

Might be cisco vpn client?

[LithiumKid1976]

hi
i cant see any software that would be causing a firewall issue.

is there a list of known software that could cause this...?

Thanks
Damein

If you can't connect to port 135 on the host it must be firewalled (this port is used for most windows operations)
it might not be the windows firewall but some 3th party firewall.

[LithiumKid1976]

hi
im still having a few users with the above issue, 78 so far.

1- Check that Windows firewall is turn off or permitting port 135 - firewall is off
1a- check that Dcom is enabled - http://www.lansweeper.com/kb/accessdenied.aspx - checked, its all ok.
2- in cmd run telnet ipaddressofmachine 135 (to make sure you can connect) - tried this...

H:\>telnet x.x.x.x 135
Connecting To x.x.x.x...Could not open connection to the host, on port 135: Connect failed


3- use the testconnection tool to test your admin/user credentials - not sure what this tool is.

i ran the wmi diag tool, have text files that i can send on ..?

[Hemoco]

Could you post a screenshot of the error details and a screenshot of the connectiontester that's working.
Is this behavior with active scanning or lsclient?

[kpulford]

I think this is the latest 3.5.1.28957 not beta.
