Hi,

try to install the patch for Windows 2008 64 bit:

http://service1.symantec.com/support/ent-security....

Just as an FYI, it was posted awhile back by a Symantec employee that this fix will be rolled into the forthcoming MR4MP2.

Thanks for fast reply :)

after installing the patch, internet connection works fine, but I still have the problem with Remote Desktop if I try to connect to this server from another server (for example Windows 2003 Std 32-bit with SEP Client), the message appear "Because of an error in data encryption, this session will end. Please try connecting to the remote computer again." if I try to connect to this server from another server without SEP Client the error doesn't appear.
Should I install any patch on a 32-bit client ??

best reagrds

Hi,

we need more details:

are you talking about a managed or an unmanaged Endpoint Protection installation?
What are the installed components? (Only AV, Network Threat Protection, etc).

Try to disable/uninstall the product components one by one to isolate the problematic one (you can add and remove components via the control panel > add/remove components > Symantec Endpoint Protection > change, the firewall installation/removal requires the reboot).
