Event ID 41025 – Conferencing Edge Server –

I was wondering about an elusive and very intermittent desktop sharing issue via the Edge Server. The only evidence of wrong doing was the Event Log on the Front End Server. The log was looping through Event ID 41025 and 41026 every 2 to 3 seconds!!!

Surely that’s not normal…

The BPA showed no evidence either. Used a simple telnet test from the FE to the CE over ports 8057 and 5062. All working.

Searching for Event ID 41025 on TechNet I found a post quoted below

“For the 41024, 41025, 41026 loop of errors, the issue was tracked down to a strange certificate issue.

On the Edge External Nic I had used one vendor’s for the UCC certificates (GoDaddy), as well I used that same vendor for the certificates on Exchange, TMG, and on the FE server Nic BUT for the internal facing edge NIC I had used a different vendor (RapidSSL) as I already had it.

I replaced the certificate from the one vendor with essentially the same thing but issued from the same vendor as all the other certificates in the deployment (GoDaddy)”

Ok, probably a good idea to check the cert assignments on the Edge Server. Turns out that I was using the same GoDaddy cert on the internal and external interfaces. Mmm…

Started to wonder if the FE was happy with that as the internal servers all used an internal CA. Two choices, either replace the Edge internal cert with one from the internal CA or export the Edge GoDaddy cert and import to the FE Personal Store. 

I went with option 2 and voila, Event ID 41025 gone!!!

About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
