Re: Intermittent E_NOINTERFACE error, possibly RPC related

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi, Paul,
Using RPC Ping utility is just for checking if there are some connectivity
issues.
To get more information, you can just add the parameter -E like this:
rpcping -s ncoantfs -v 3 -E

However I found that I missed an important paragraph of your saying:
" Once this happens, all calls from the server application to the client
application consistently fail similarly and repeatedly, even if both
applications are restarted, until the client is rebooted."
In addition to Anti-virus software influence, I recommend that you check if
you can telnet to the server TCP port 135 at that time. Also, this issue
may be able to dynamic TCP port and firewall. Please disable firewalls on
both sides or specify a TCP port range allowed in your firewall and see if
this issue persists.
Please refer to:
Using Distributed COM with Firewalls

To monitor the communication, you can also use NetMon. You can install the
tool from Add Remove Component or download the tool from:
Microsoft Network Monitor 3

Since the issue is complex and occurs intermittently, you may also consider
to contact Microsoft Customer Support Services (CSS) via telephone so that
a dedicated Support Professional can assist you in a more efficient manner.
Please be advised that contacting phone support will be a charged call.

To obtain the phone numbers for specific technology request please take a
look at the web site listed below.

If you are outside the US please see http://support.microsoft.com for
regional support phone numbers.

If you have any other questions or concerns, please feel free to let me
know. It is my pleasure to be of assistance.

Best regards,
