i have a laptop that is locking up and having a hard time reading the local and network drives when going through my computer or explorer. he see 2 local drives and 14 network drives. he is in a remote branch and there is site to site ipsec vpn in place. other users in the same remtoe office do not see these delays or lockups. he is on wireless and i have also seen the wireless connection go from 54Mbps to 2Mbps and then back up.

Did you run hard drive diagnostics on the hard drive?
Depending on the brand of laptop, you may be able to download the manufacturer specific hard drive diagnostic.

If the problem is not hardware related, try using msconfig to disable a lot of programs seeing if this helps with the speed:

Click the Start button then the ‘Run…’ menu choice and type in msconfig
This runs a program that will give an option to disable programs not needed to run Windows. If not sure what programs need disabling, it’s best to leave them.
Note here: the two tabs to be concerned with are the ‘Services’ and ‘Startup’ tabs.
On the Services tab, check the box, [  ] ‘Hide All Microsoft Services’ to prevent disabling services Windows needs to run.
On the ‘Startup’ tab, you can uncheck as much as needed here.

If it still runs slow after this, it might still be a problem with the hard drive even though the diagnostic is not finding any errors, or possibly even a virus.

The problem is the network drives...

When you open my computer and have network drives connected Windows will begin reading the tree structure of the network drives (even if you are not looking in them) and this can take some time especial if there are lots of sub directories.

Does this user really need access to 14 network shares?

Rob HutchinsonDesktop SupportCommented:
Sorry, you mentioned that the problem was also the local drives.

Can you give the user a new login profile annd remap the drives to see if this helps?

To do this, reboot the computer and login using a different login like Administrator.
Go under the Documents and Settings folder and rename their profile folder or move it to another temp folder. For example, make a folder called C:\TempSave and move the user's profile folder under here.

After doing this, logout the Administrator login and have the user log back into the computer.
This first time logging back in might take a while as the user's folders will have to be recreated.

After logging them back in, copy the Desktop and Favorites folder from their old profile that you copied to the C:\TempSave folder.

At this point, I'd see if accessing the local drives was still slow. If not, then try readding the old drive network mappings back( you should make a print screen of the drive mappings before getting rid of the old profile).

If the restored network drip mapping access is still slow, then and the local drive access is also also slow like before then let me know.

If the restored network drive* mapping access is still slow
Erik BjersPrincipal Systems AdministratorCommented:
I just had this exact same problem yesterday at one of our remote sites (very bad WAN connection).  The user had 2 network drives mapped and everything was going slow on their computer.  I used "NET USE * /DELETE" to remove all network shares and instantly everything started working normally.  

This problem can be exasperated if you have an AV application that scans files as they are accessed because it will try to scan files on the network drive.

Rob HutchinsonDesktop SupportCommented:
I may not be the number of network drive mappings, but it could be their AV software. We have users here who have every single possible drive letter mapped and their computer still runs fine.

Are those users on the LAN or connecting through VPN?

The user that dirkdigs is having a problem with is at a remote site with 14 network drives mapped (I am assuming back to the main office servers).

In a LAN environment it will not be a big issue to have lots of network drives mapped, this may slow things down a little when using explorer but it will not be very noticeable.  In a WAN environment with VPN you are looking at a much smaller pipe for all that data to go through and if these shared folders are large (number of subfolders and files not disk space) then this problem grows exponentially.

The user I had the problem with is working in a remote site that has around 128Kb of bandwidth and that is shared so just having 1 mapped drive to the home office was killing her computer performance (explorer working hard and draining other resources).

with 0 network drives it runs fine. it is definatley the # of network drives. it is all over VPN so this doesn't help. AV is Symantec Endpoint protection.

No real fix right now but this page will give you more info on why this is happening
