On-demand GlobalProtect and Mapped drives

GeorgiosFakis — Wed, 26 Feb 2020 14:47:35 GMT

Hello all ,

Having issues with some users where they have mapped drives but after they connect to global protect they don't work.

If they unmap and they map again it works .

When doesn't work after connecting to globalprotect if they ping the IP of the server that they have the mapped drive it works but SMB it doesn't .

We have on-demand globalprotect, SSO disabled of course and we allow netbios, SMB and I don't see any blocked traffic.

I have tried to search that and I don't want to say to the customer to fix that with scripts net use because all users are using their own shared folders.

@GeorgiosFakis,

What version of Windows are they using? Does the drive show as disconnected and simply won't connect, or does it simply hang when they try to access the drive? If the user restarts explorer.exe after they connect to GlobalProtect can they access the drive?

I'd also ensure that the group policy you are using to map these drives is set to Update instead of Replace. There was an instance a while back where the Group Policy updating in the background with a Replace action would cause the drive mapping to be lost like you are describing here.

Hi ,

Users most of them have Windows 10 and they show disconnected .We have not tried to restart this service but what we have tried to access through run command \\shareX\ .

We don't have standard mapped drives, each user adds their own for their work.

@GeorgiosFakis,

When someone runs into this again, try restarting explorer.exe and see if you are able to access the mapped drive again.

Hi,

We tried with one user and didn't work but you know what they say? Pulse Secure was not causing that issues .

I have isolated the issue to specific shared folders. All common shared folders they are connected after user connect to global protect.I have asked the server team to check as well these specific shared folders and from what it seems is the sync between host and AD.

I am having the exact same issue but mine is "well Sonic Firewall works". Makes it hard to sell a new VPN solution to management when things like this don't work.

So I want to share that I believe we have found the solution for mapping our personal drives without having to have the pre-logon. I had one of my admins create a .vbs file that will pull the home drive mapping info from AD. then we added a registry key into the install package to point to the .vbs file to execute this post-vpn-connect. https://docs.paloaltonetworks.com/globalprotect/7-1/globalprotect-admin/set-up-the-globalprotect-infrastructure/deploy-agent-settings-transparently/deploy-agent-settings-to-windows-endpoints/deploy-scripts-using-the-windows-registry

Hi George - did you ever resolve this? Same problem over here.

Hi ,

We found around 100 users having this issue where mapped drives had their COMPUTER name like alias and linked to one of the servers for personal host space . Basically , helpdesk instructed them how to change that so the mapped drive have a normal path .

I don't know how it was working before with Juniper Pulse but with GP we had issues. All the other mapped drives that was from the AD policy were ok after connecting to GP .

Having the same issue here with PanOS 9.1.5 and GP 5.2.2.

We are replacing a Sophos firewall and this just worked before it's hard to sell a PAN solution with this kind of issues.

@Jason.Holcomb would you mind posting the content of that .vbs-file, or at least describe what you meant with "that will pull the home drive mapping info from AD".

I think we might need to do something similar.

We have file called Map_Home_Drive.vbs which is installed on all the machines that the registry points to. In AD we have the home drive mapped (I am not the AD admin so I am not sure which field they populated but I know the drive is mapped in there)

'--- START

DIM strHomeDrive, strRemoteShare

SET objFileSys = CreateObject( "Scripting.FileSystemObject" )
SET objNetwork = CreateObject( "WScript.Network" )

'--- Wait a short time to connect to the network
WScript.Sleep( 15000 )

'--- Get Active Directory information
SET objSysInfo = CreateObject( "ADSystemInfo" )
SET objUser = GetObject( "LDAP://" & objSysInfo.UserName )

strHomeDrive = objUser.HomeDrive
strHomeShare = objUser.HomeDirectory

WScript.Echo vbCrLf
WSCript.Echo Now()
WScript.Echo "strHomeDrive: " & strHomeDrive
WScript.Echo "strHomeShare: " & strHomeShare
WScript.Echo vbCrLf

If objFileSys.FolderExists( strHomeDrive ) Then

WScript.Echo vbCrLf
WScript.Echo strHomeDrive & " is already mapped - DONE"

bolHomeShareMapped = FALSE

Do While LoopCounter <= LoopTotal

WScript.Echo vbCrLf
WScript.Echo "Mapping home share - attempt " & LoopCounter & " of " & LoopTotal

WScript.Echo "Home share found..."

'--- Map home share if it can be seen
WScript.Echo "Mapping to home share..."
objNetwork.MapNetworkDrive strHomeDrive, strHomeShare, False

'--- Verify home share is mapped
WScript.Sleep( 5000 )

WScript.Echo "Home share mapped..."
bolHomeShareMapped = TRUE
Exit Do

End If

Else
