kalamiti <kalamiti@xxxxxxxxxxxxxxxxxxxxxxxxx> stated, which I commented on
below:
I am trying to run an inventory program and it is failing because of
WMI errors the seem to be RPC related. I have been testing the
problem with wbemtest. I get the RPC unavailable error and in the
event viewer it shows up with this error DCOM was unable to
communicate with the computer name using any of the configured
protocols. All od the port are unblocked between the servers and the
one I am using and I have tested some ports with telnet: 135,139,445.
The account has admin access and can be used to remote and of the
servers I am trying to inventory. Please help
Usually RPC errors are due to name resolution or blocked ports. Keep in
mind, the ports you mentioned are not the only ports required. Besides
authentication traffic ports (Kerberos, LDAP, GC, etc), it also needs UDP
1023 wide open.
Back to name resolution: What DNS addresses is the workstation running the
app using in it's IP properties? Is this all setup in an AD environment? If
so, and using the wrong DNS addresses, this can be the cause. But there are
other issues that can cause it to that is related to DNS and AD
misconfiguration.
So it depends on your environment, configuration and infrastructure. If you
can elaborate and offer an ipconfig /all of this workstation for starters,
and possibly of one of your local DCs, we can see if that part is configured
correctly. If going across a router to authenticate/connect, then also make
sure all ports are opened as well as leaving the MTU settings to 1500. ADSL
is also known to cause RPC issues across a VPN using ADSL as one of the
endpoints.

Instead of the website you're using, I suggest to use OEx (Outlook Express
or any other newsreader), and configure a news account, pointing to
news.microsoft.com. This is a direct link to the Microsoft Public
Newsgroups. It is FREE and requires NO ISP's Usenet account. OEx allows you
to easily find, track threads, cross-post, sort by date, poster's name,
watched threads or subject.
It's easy:
