Lync Server 2010 RC currently has no Resource Kit. So you may try to use OCS 2007 R2 Resource Kit. But when you try to install it on Lync server, you will failed with error that
Microsoft office communications server 2007 r2, resource kit tools installation or uninstallation requires that VC++ 2008 redistrbutable is already installed. either use setup.exe for installation or run vcredist_x86.exe included with the product to install the redistributable.
So let’s take another way to do that. Exactly, we do not need to install the full Resource Kit but the tool called snooper.exe inside it. How about to extract this msi packet without install? (you may able to remove such detection in the msi packet with orac tool)
OCS 2007 R2 Resource Kit is a MSI packet, so you can not use winzip to extract but msiexec.
msiexec /a PathToMSIFile /qb TARGETDIR=DirectoryToExtractTo
msiexec /a OCSResKit.msi /qb TARGETDIR=C:\OCSResKit
after the extraction process finished, you can copy the snooper.exe in “C:\OCSResKit” to “C:\Program Files\Common Files\Microsoft Lync Server 2010\Tracing”, and now you can trace with Lync Server 2010.
