Windows Script Host Error


Recommended Posts

Lately more and more issues have been occuring on various clients involving the Windows Script host. Users are issued a script that applies when they first login. This script handles the mapping of 6 or so mapped drives. Unfortunately, lately more and more computers have been having issues applying this script, when someone logs off and then at some point someone logs in (Doesn't matter how long they wait).

This issue doesn't occur on the first boot / first login of the machine... but will always occur thereafter. It doesn't seem to occur quite on every machine, but it happens on more and more now.

Being for a police department, this issue is becomming more critical, due to the amount of users logging in and out of the machines... and if the drives don't get mapped, they lose crucial access to their reports and other files.

Can someone please help me figure out a resolution to this problem?

Sure!!!

(1)

(2) Dim objNet

(3)

(4) Set objNet = CreateObject("Wscript.Network")

(5)

(6) objNet.MapNetworkDrive "H:", "\\********\HOME"

objNet.MapNetworkDrive "I:", "\\********\Apps"

objNet.MapNetworkDrive "Q:", "\\********\formdata"

objNet.MapNetworkDrive "S:", "\\********\schedulesoft"

objNet.MapNetworkDrive "T:", "\\********\Traffic"

objNet.MapNetworkDrive "W:", "\\********\idphoto"

Which is line 6? is it objNet.MapNetworkDrive "I:", "\\********\Apps"? Do machines that are having this problem always choke at line 6? there might be something wrong with that server/share

I've added the line numbers in the script so that you can see where line 6 is. Line 6 is the first line that begins the mapping of the drives. I don't believe that there is a problem with the server, I believe this problem lies wiht one users settings not leaving when the user logs off, then someone else logs in and it negates itself. They always do choke at line 6, but again that's where the drives are beginning the mapping. The share itself is working correctly.

Are these servers all in the same domain? Are the users all logging into the same domain? Are they on the same subnet? What are you using for netbios name resolution? Wins or broadcast?

On a machine that you get the error on - what is the output of just doing a net view \\servername after the script failed?

Are the drives already mapped? To somewhere else? When the script is trying to run? If so so you could check for this, and or just do a simple remove and then add, etc..

Once the user has logged in - what drives are listed?

net use

If you add "On Error Resume Next" does it die on the next line?

1) The mapped drives are really all pointing to just the 1 server, but in any case yes it's all going to the same domain.

2) Yes, again they're on the same subnet.

3) While we do have WINS Enabled, I think initially it is Broadcast until I manually add the WINS information to the adapter... I have not found an automatic way to do this so I don't have to go to all machines to add WINS information.

I'm relatively certain that when you do the net use command it says "No Network Provider Accepted the Given Network Path"

Technically you can say they are mapped. User logs in. Does what he needs to do. User logs off. A second user logs in, and error message occurs. Almost as if, "Hey, user logged off but the drives are still mapped... user 2 logs in, error appears, then the mapped drives disappear.

net use

After the error occurs, only the local drives appear... no mapped drives appear as they should be.

Ok, I don't know scripting at all... where do I put this line???

Thanks for your help!

What you probably need is a "cleanup" type script. If you are assigning drives at logon, you should remove them at logoff to prevent errors.

Set net = WScript.CreateObject("Wscript.Network")
net.RemoveNetworkDrive "DRIVE LETTER:"
WSCript.Quit

I'd at least try it and see what happens. :cool:

This is the code I use.

Dieterich: Where would I put this information? Would this be at the bottom of the logon script I already have? I'm sorry, I'm not familiar with scripting at all...

MazX: Same thing, I am not familiar with scripting. Is the only thing I Need to change is near the top where you have the mapped drives? At least in your script, it's just M... Is that the only thing that I modify? I see at the top it states that this goes as a group policy for the users. Can this script also be applied as a script specified to be processed under the Active Directory Users & Computers under the profile tab?

Change here:

  Quote
' ==================

' DEFINE DRIVES TO MAP:

' ==================

Mapit "m", "\\server\share", "", ""

This says what drive letter to use and the path to the share.

And here:

  Quote
mDrive = "M:\"

Set oShell = CreateObject("Shell.Application")

oShell.NameSpace(mDrive).Self.Name = "Share 123"

This says that drive M should be called "Share 123" rather than "Share 123 on Server"

You save the code into a text file. Then rename that file map_drvs.vbs

In AD U&C you select the OU that you want this script to apply to. Create a GPO that applies to that OU.

In the GPO you set the Logon script (in User Config) to use the map_drvs.vbs

When users are placed in this OU the script will be run at login.

When a user is removed from the OU, the script no longer applies and the drive is not mapped.

When the user logs on and is not connected to the network, the script will not run and the drive is not mapped.

For that second part I have to edit, how would that look like? I'm thinking by your example, it would have to look like this:

Line 1: Drive A

Line 1:

Line 1:

Line 2: Drive B

Line 2:

Line 2:

Line 3: Drive C

Line 3:

Line 3:

Is that correct?

And also, the reason I ask where it can be applied is because right now every single user that logs in has the logon script applying to it inside of the profile options in ADUC... no GPO is applying that. Can't I just modify the existing logon.vbs so I don't have to go to every user and remove the logon script? It's only modifying their drives anyways.

You can. It would be better to use GPO's though.

Alright, getting some other strange occurances here!

Well, I have a test account that is in it's own OU. This account NO LONGER has the original logon script that was defined in Active Directory being applied to it. I setup MazX's script successfully as a GPO, and applied it to the same Test OU that my test account is apart of. When I login to a machine remotely (which is the machine I use at the office), everything seems to work fine, except 1 thing: I had set the GPO to show what commands were being processed from the login script... I take it the script is made so that it won't show it regardless?

Well I had someone login to the test account on one of the problematic machines that always got the Script host error... and sure enough, the error occured again. But how?!?! It is the same exact error I have above, but logon.vbs is not being utilized! It isn't setup in the profile at all, so how would it be getting the error?

Now I'm out of ideas. :(

    • AMD Ryzen AM4 16-core 5900XT processor has never been priced cheaper by Sayan Sen While AMD's newest processor platform with DDR5 and PCIe 5.0 goodness is AM5, the preceding Socket AM4 continues to be a great option for gamers shopping on a lower budget. One of the most powerful AM4 desktop chips, the 16-core Ryzen 9 5900XT, is currently priced at the lowest ever at just $230 (purchase links down below). The Ryzen 7 5900XT is based on the Zen 3 architecture supports DDR4, PCIe Gen4, and offers very good performance in both gaming and productivity. While users may not expect the same level of gaming throughput or latency improvement as the 5800X3D, it is certainly possible that titles that utilize more than 16 threads will favor the 5900XT over the 5800X3D. And the 5900XT has plenty of L3 cache as well at 64 MB. So while not 3D stacked V-cache, it should still be a decent gaming chip. And all that cache as well as cores/threads will be excellent for non-gaming tasks of course. The CPU has a base clock of 3.3 GHz and boosts up to 4.8. It has a TDP of 105 watts so the available power envelope certainly helps with that. It can tolerate temperatures of up to 90 °C and there is no boxed cooler with it. So you need an aftermarket one, ideally a 280 mm or 360 mm AIO liquid cooler or an excellent air cooler. Also since this is a 16-core 105-watt chip, make sure to run it on an AM4 board that has good quality VRM and cooling with lots of power (ideally an X570 motherboard). Another consideration is that it does not have integrated graphics so you need a separate dedicated GPU for display out. Get the AMD Ryzen 9 5900XT at the links below: AMD Ryzen 9 5900XT - No Integrated Graphics Desktop CPU Processor - 100-100001581WOF: $229.99 (Amazon US) || : $279.00 (Newegg US + Corsair 32GB DDR4-3200 RAM) This Amazon deal is US-specific and not available in other regions unless specified.
