Active Directory Users & Computers slow over GlobalProtect

L1 Bithead

We are experience an issue that I am curious if anyone else has encountered. When any of us IT folk are VPN'd in via GlobalProtect (tested on different internet connections, hardwired and wifi) whenever we open up MSFT Management Console Active Directories Users & Computers, it takes about 5-7 minutes to open.  I can see the traffic in our traffic logs on the Palo, nothing denied, it just takes a long time until it opens and runs painfully slow once opened. 

 

If anyone has encountered this before if you could point me in the right direction that would be great, I will update if I do find anything.

 

Thanks,

"dsa.msc /server=" is the best option. The weakhostsend either enabled or disabled is useless. This was not an issue prior to the upgrade to 5.2 so they changed something and need to address it.

Is there any new information about this? We're on 5.2.4 and we still have this issue.

We had the same problem, and based on what we read here in this thread, we just disabled IPv6 on the virtual network adapter for GlobalProtect, and it resolved the issue.  We are two for two with this solution so far.  If all else fails, just disable IPv6 on all your network adapters...assuming that you do not use IPv6, of course.

We experienced this issue as well on GP 5.2.7, PanOS 9.1.10.

 

The registry command doesn't work because it won't run as admin without "start-process powershell -Verb RunAs", which still pops UAC prompt as expected.

 

Running the command manually didn't work for us either.

 

Found that running "Set-NetIPInterface -WeakHostSend Disabled" and "Set-NetIPInterface -WeakHostReceive Disabled" fixed the issue. Determined these commands worked because it disabled weak host send and receive for IPv6 as well as IPv4.

 

Disabling IPv6 on LAN and WiFi adapters fixed the issue.

This is something that palo should address.   I've tried the split tunnel and the resolution still doesn't work for us.   Only thing that works is disabling IPv6, which is unacceptable in todays age.

Disable IPv6 to fix this on the WiFi adapter to fix this.

I can't take credit for this fix. Found it on redit

Hi,

 

With GP 5.2 and higher you should not have anymore Problems, see: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g0000008UNoCAM

My company is on GP 5.2 and still had AD slowness until disabling IPv6 on the Wifi adapter.

Hi @NathanielM ,

 

as in the other articel is writen, it depends on the DNS Split Tunnel Feature setting. It is not written how it depends, but if you read this article: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000HBJ5CAO&lang=en_US%E2%80%A... maybe you find the right Split Tunnel Option. I can not test, but i have a customer with the same problem. I have to test this also with that customer, if he has time.

Hello Scott

 

As we has simlar issue on W10 with GP 5.1 or 5.2 for some users. I read this email about "Dug into our DNS..."  Is this setting on Corp DNS server ? or on Firewall. As IP scope is assigned by PANFW.  I guess it should be some setting on FW ? Please share your fixed setting if you can.

 

Thank you

 

Daniel
