About Me

TsooRad is a blog for John Weber. John was a Skype for Business MVP (2015-2018) - before that, a Lync Server MVP (2010-2014). My day job is titled "Technical Lead, MS UC" - I work with an awesome group of people at CDW, LLC. I focus on collaboration and infrastructure. This means Exchange of all flavors, Skype, LCS/OCS/Lync, Windows, business process, and learning new stuff. I have a variety of interests - some of which may rear their ugly head in this forum. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army. I have a fancy MBA. One of these days, I intend to start teaching. The opinions expressed on this blog are mine and mine alone.


AntiVirus and Lync

Right from the online CHM file entry on virus scanning exclusions.  I had a bit of trouble finding this, even though I knew it was there.  A colleague reminded me of this, so I thought I would throw up a quick reference so I can always find it.  I had a client ask me this question, and my response was “the entire install structure, the standard SQL exclusions, and the file share location.

Here is the link to the official material, and below is the data copied from that link so I don’t have to go hunting for it!  Note that the Lync file share is not on this list; however, I have seen some issues with meeting content when the server is actively scanning that location.  I cannot say for certain that the virus scanning on the server was causing the issue, but I do know that disabling the virus program on the server fixed the issue.  On the client side, it appears that some client virus engines get in the way of certain Lync functions unless you specifically add the Communicator.exe program to the engine’s allowed programs.

Specifying Anti-Virus Scanning Exclusions

To ensure that the antivirus scanner does not interfere with the operation of Microsoft Lync Server 2010, you must exclude specific processes and directories for each Lync Server 2010 server or server role on which you run an antivirus scanner. The following processes and directories should be excluded:

  • Lync Server 2010 processes:
    • ASMCUSvc.exe
    • AVMCUSvc.exe
    • DataMCUSvc.exe
    • DataProxy.exe
    • FileTransferAgent.exe
    • IMMCUSvc.exe
    • MasterReplicatorAgent.exe
    • MediaRelaySvc.exe
    • MediationServerSvc.exe
    • MeetingMCUSvc.exe
    • MRASSvc.exe
    • OcsAppServerHost.exe
    • QmsSvc.exe
    • ReplicaReplicatorAgent.exe
    • RTCArch.exe
    • RtcCdr.exe
    • RTCSrv.exe
    IIS processes:
    • %systemroot%\system32\inetsrv\w3wp.exe
    • %systemroot%\SysWOW64\inetsrv\w3wp.exe
  • SQL Server processes:
    • %ProgramFiles%\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn\SQLServr.exe
    • %ProgramFiles%\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\Bin\ReportingServicesService.exe
    • %ProgramFiles%\Microsoft SQL Server\MSAS10.MSSQLSERVER\OLAP\Bin\MSMDSrv.exe
  • Directories:
    • %systemroot%\System32\LogFiles
    • %systemroot%\SysWow64\LogFiles

Confusing title! AV in the Lync context is audio/video :P

@Harry, I changed the title; you're right, it was confusing.
