Unable to open the NIC adapter [\] for sniffing indicates that it didn't know which NIC to begin listening on.
On the CRS server, go to C:\Program Files\cisco\desktop\bin and launch
PostInstall.exe. Click OK to confirm the IP Address appears correctly, and another window will appear. Under VoIP Network Device, there's a drop down where you should see the NICs on the server. Is the active
NIC being used for monitoring and recording selected?
