kb3199088 breaks test-csucwaconference and hence the watchernode/monitoring

[JonatanV]

the latest update to core components breaks test-csucwaconference
i have verified it on two separate systems

after the update you get the following error:
Test-CsUcwaConference -TargetFqdn fepool1.domain.com -ParticipantSipAddress sip:watcher2@domain.com -RegistrarPort 5061 -OrganizerSipAddress sip:watcher1@domain.com -Authentication TrustedServer

Target Fqdn : fepool1.domain.com
Target Uri : https://sfbwebint.domain.com:443/CertProv/CertProvisioningService.svc
Result : Failure
Latency : 00:00:02.9260389
Error Message : Failed conferencing activity.Method not found: 'Void Microsoft.Rtc.Internal.Ucwa.ClientModel.Interfaces.InvitationDetails..ctor(System.String, Microsoft.Rtc.Internal.Ucwa.ResourceContract.CallType, Microsoft.Rtc.Internal.Ucwa.ResourceContract.Importance, System.String)'.
Diagnosis :

uninstalling the update again "resolves" the issue

this is still an issue after the latest may updates for s4b

[#2]

It would be great to get some feedback on this issue. Especially if its known by MS and will be fixed soon :)

Have received this error after applying SfB server CU5 on Saturday, but I cannot find the KB3199088 installed on Skype servers. 

[#4]

Do you mean the CU5 update?

[#5]

I would be very interested to hear if this problem has been resolved!

[#6]

Did you have to back out the full CU or just one component? if one component which one?

[#7]

Check .NET version, and ensure you have .NET 4.5.2 installed.  Missing method error indicates likely related to core code.  Error is in similar range to https://support.microsoft.com/en-us/help/3209492/step-1-of-sfb-2015-deployment-wizard-fails-after-yo... Would recommend installing .NET 4.6.2 as that is supported with SfBS 2015 servers per https://blogs.technet.microsoft.com/nexthop/2016/02/11/on-net-framework-4-6-2-and-skype-for-business....

Be aware of if .NET 4.5.2+ are installed, the May 2017 Security rollup for .NET results in this KB (

https://blogs.technet.microsoft.com/uclobby/2017/05/24/lyncsfb-server-event-41026-ls-data-mcu-after-...) happening, so plan workarounds accordingly.

Hope this helps.

[#8]

You only have to uninstall the sfb core components update to make it work again.

[#9]

Hi Nicholas

Thanks for your reply

As far as i can tell the error is not related to .net. However i do believe that its a change or a bug in the core code.
Btw you can also run the test manually from another skype server, like front end, and you will get the same error.

[#10]

Thanks for the info.  After some testing, don't think it is .NET version related in this instance although the majority of the time we see that exception, it tends to be the instance.  Regarding rolling back Core Components, I would be careful there.  The local RTCLOCAL/LYNCLOCAL instances may have been updated, and rolling back CU code to a prior CU can result in issues if there were changes made that result in not calling a stored procedure, etc., in a manner expected.

Can you run the Test-CsUcwaConference cmdlet manually specifying the -OutVerboseVariable cmdlet, passing the verbose output to variable (reference cmdlet documentation for specific syntax), and then paste the results up to the exception and call stack?  Don't need specific domain information from the output, so feel free to scrub it.

[#11]

Jonatan,

After performing  additional research, it is likely the issue you are experiencing is related to a product issue in Skype for Business Server 2015.  The stack trace from the error is going to be key here.  While the Method Not Found piece matches, it doesn't contain as much information as an output of the verbose variable that is a parameter with the cmdlet.  This will allow me to determine if it matches up with the particular stack trace related to the issue that we have been working on.  If you could provide that while replacing any PII type data (domain names, server names, user names, etc.), I’ll be able to provide a better answer.

If your issue is related to the issue we've been working, we are hoping to release a fix in the next Cumulative Update (CU) for Skype for Business Server 2015.  Please ensure to note the following caveats.

• Any timeframe references, CU references, etc., are tentative.  They can change without notice.
• Fixes can be removed from updates if they don't pass validation and regression testing, etc.

This matches up with the call stack of the issue we've been working, so should be related.  We are hoping to release a fix in the next Cumulative Update (CU) for Skype for Business Server 2015.  Please ensure to note the following caveats.

• Any timeframe references, CU references, etc., are tentative.  They can change without notice.
• Fixes can be removed from updates if they don't pass validation and regression testing, etc.

I hope this helps!

[#14 · Accepted solution]

@JonatanV, this should be addressed in the December 2017 Cumulative Update (CU6) that is available for download.  See the following.

Update Page:  https://support.microsoft.com/en-us/help/3061064/updates-for-skype-for-business-server-2015

Thanks Nicholas. CU6 did indeed solve the bug again.

Hello,

We are running Lync 2013 with CU (Jul-17 – 5.0.8308.992) and is getting the following similiar error message (below).

Do you know if the fix in Skype for business CU6 also was done for Lync 2013 ?

Hi Mattias

I have no idea, and i have decommissioned every lync 2013 server so i cant verify it either.
