Procmon scan smb request

Question

Hello,

I have an issue on a fileshare server, users are complaining about latency, especially when transferring files to the fileshare server,opening files, or modifying files.

I want to launch a procmon on the user workstation to see what what happen when a file is being opened,modified or transfered.(i'm suspecting Antivirus)

Could you please tell me what query on the filter of procmon i should do to target the smb path? cause i think procmon doesn't support the classical UNC path => "\XX\X"?

Thanks
