Hi All, Our file server is running Windows 2012 R2 and was previously using McAfee Anti Virus and its situated in a Data Centre. Our computers in our office had 0 problems accessing those files previously. As soon as we installed Kaspersky Endpoint Security on our file server, our computers could not connect to the mapped network drive. We can not ping the File server in command prompt either. If anyone could help with this, i’d greatly appreciate it. Many Thanks.
