Goodday,

We were experiencing some serious issues with our file server after updating to the latest version yesterday. We updated our server yesterday roughly around 16.00 local time but our problems did not begin untill 10.00 this morning. Our file shares were inaccessible (even from the local machine were the shares were visible). After two restarts (during business hours!) and two attempts to uninstal the SEP software (as we suspected that it was the cause of our issues) we found this article:

http://www.symantec.com/business/support/index?page=content&id=TECH102742

The article suggest that this problem is present in version 11.x but we've found that it is present in the latest version aswell. We had to download a tool from symantec to remove the software from our server. The software was removed roughly 1 hour ago and the shares are currently still working. The purpose of this forum discussion is just to inform you of our problems and hopefully it could help someone in someway. The tool to remove the SEP software is called "CleanWipe" from Symantec.

Did you install Network threat protection (firewall component)?

Have you tried running only antivirus and antispyware on this server?

See this articles does help you

Unable to access shared folders or resources with Endpoint Protection 12.1 Small Business Edition

SEP 12.1 blocks file sharing traffic

Have you disabled the firewall?

Hello Dennis,

Do you need more help here ?

Hi,

We also have the same issue with Windows Server 2008. The issue is intermittent and we cannot replicate the issue for isolation. Shares become inaccessible and printers, you can remote and telnet smb 445 service but you cannot browse the shares. we've been sending logs to the support but it seems like they havent figured out anything yet for 2 months now. We are running version 12.1.4100.4126 without the Firewall component.

I would like to know if anyone else is expereincing this issue?

Thanks!
