UCA disconnections

[ralph]

I'm starting to investigate an issue with our own UCA.  V6.0.30.0

This just suddenly stopped working last week.
What happens is when I fire up my client it disconnects after about 5 seconds.  We can never really get it online.
This appears to be happening to all our users at the moment.
This was working with no known network changes.

Any clue where to look for the cause or which logs to start checking?

If this is a VM, I'm guessing it's somehow corrupted.  If possible, I'm wondering if restoring an earlier snapshot of the VM is the way to go.  If not, build a fresh MAS VM and restore the DB from this MAS - hopefully from before this happened.

Even though we have a VM MAS 3.0 and an physical AWC 3.0, I still manually backup the DBs of each once a month - same with our 5000.  Beginning of every month.  It's one of the few manual un-automated things I do.

probably doesn't help but the only time i have seen this is if the UCA is not using the company DNS server as the PC's will be.
If you find out what causes it let us know.

Cheers!

Is it a MAS?

Try to stop MBG service in that case. If it resolves, try to disable UCA support in MBG.

I've seen many installations where UCA and MBG are both trying to open port 36008. If you disable UCA support in MBG, it will stop trying to open that port.

Log can be found in the User>appdata>remote>Mitel>UC>log

and if you have a certificatemismatch error then open MMC-Certificates for Local User and Machine. Delete old certifications and registry then reinstall UCA or just try to log in
