There is a patch available that fixes some bsod issues with 9.5 and eps. Please contact support to obtain a patch. Note the patch is not specific to symantec.
have tried these patches before. but I confirmed it is conflict with SEP 11 RU6 MP3
Most of my computers have Symantec 12.1 and Windows 7 and I have not had a conflict with them and 9.5.
I also run my Symantec firewall wide open.
I have a few probably less then 1000 computers that have symantec 11 and they are running XP and I know alot of them have been updated to Landesk 9.5 with no conflicts as far as blue screen, just with scans not quitting.
I also have the firewall running wide open on them.
I'm still getting Symantec and Landesk agents updated.
That's why I think BSOD situation just found at SEP 11 RU6 MP3 update. I think the latest SEP 11 works smoothly even LD agent 9.5 installed.
