Network problems from 12.1.2 fixed yet?

Created: 15 Jan 2014 • Updated: 17 Jan 2014 | 11 comments
This issue has been solved. See solution.

We're on 12.1.1 and though testing went well, when I upgraded the office to 12.1.2 last year we got hit by the nasty network bug that affected XP and made the network very slow. Link here: http://www.symantec.com/business/support/index?pag...

Though a very difficult and slow process I got all of our machines rolled back to 12.1.1. I then skipped 12.1.3 and waited for 12.1.4. Well it's out now but I'm still seeing forum posts complaining of network speeds and firewall issues with 12.1.4. When are those issues going to be fixed so I can upgrade past 12.1.1? Since the problem only affected certain machines I can't rely on testing to tell me if this version is going to cause problems on our network or not, and the roll back procedure was so incredibly painful that I'm not about to risk having to do it again.

Anyone have any information that might help me out here? If Symantec has finally implemented a system that allows for automatically rolling an entire network back to a previous version that would be very helpful. Also, having the ability to delete the latest version from the endpoint manager would be nice too, since the latest version at that time was a very broken one that needed to be deleted.

Some have complained of the problem in RU4 but I don't any issues with it. It was a problem in 12.1 RU2 MP1 and fixed RU3. That I did have a problem with and RU3 fixed it. Been fine since.

You'll have to test on a client or two to see if it affects you.

I did testing before upgrading to 12.1.2 and it didn't do any good since it didn't affect every machine. The ones I tested worked just fine. It would be nice if testing on a few machines was good enough, but for this product it's not. If there was an easy way to roll back an entire network I'd just go for it, but accomplishing that is just far too painful and time consuming to risk it.

It's tough to say what the result is. The only time people come on here is to report an issue. I've never seen someone report that all was working fine. I've seen a few threads complaining of RU4 network issues. For me, it has worked as expected. Best advice, aside from testing, I can offer is to follow up on the RU4 threads with the same issue and perhaps put in a support call to see what they know.

After further testing, with large file sets (1+ Gb) I can confirm the issue does still exist.

With the fw enabled, copy speeds are around 3Kb, with it disabled, they kick back up to normal.

I'm very surprised to say the least that this hasn't been fixed.

The issue with 12.1.2 existed even if the FW was turned off. The only way to fix it was to roll back and remove the bad network drivers from the system. Did you happen to test with the FW deactivated as well?

.Brian's picture

Yep. With the fw enabled, performance is awful. With is disabled, works as expected.

I'm putting in a support call today

Would you say it's safe to upgrade if we do not use the FW?

.Brian's picture

All else appears normal so yes I would say it should be OK. This firewall issue has been around for awhile though..

SOLUTION

I opened a case and we tried a few different things, none of which were successful. I collected the advanced debugging logs and sent them over to Symantec. My case was kicked up to the backline team.

I'll keep this thread updated as we go.

You can also PM me for further info if needed.

My issue has been resolved.

I had the option checked to "Scan files on remote computers"

AV policy >> Auto-Protect >> Network Settings

Once unchecked, transfer speeds were back where they should've been.

RU4 is running perfect on my sites and there is no complaint against network issue.

Best advice is that before implement on Production Server, try to create a test server and add some clients under that testing
