We do run Trend as an anti-virus in our company, but knowing that it could potentially cause scanning issues we uninstalled it from that machine because it is a designated Laserfiche scanning station. There is no "real time protection".
The session I'm having trouble with only gives me the RCP error when it's on a different user profile. I may be missing something as far as permissions/authentication goes. What would cause the RCP error to happen in one user account, but not another when they're using the exact same Quick Fields session?
