W7 "Browse for Folder" does not see all network drives?

By CharlieSpencer ·
Bear with me; I have to recreate my original question post and I don't recall all the details.

I'm trying to update a driver on a W7 SP1 system. I have the driver on a shared network drive. I start the Driver Upgrade wizard and tell it to let me pick the driver. When the 'Browse for Folder' dialog box appears, I try to navigate to the desired network drive but it isn't listed. Other network drives are accessible in the dialog box. The desired drive shows up in Windows Explorer and other dialog boxes.

I found some references to this being a quirk of dialog boxes for MMC snap-ins, along with an MS KB article. (Sorry, I lost the article number with my original post.) Unfortunately, the referenced hotfix would not install on my system, claiming it didn't apply.

The drive in question is assigned in my AD profile as my home directory and assigned the letter 'I'. The other network drives are assigned by batch file at logon. I can successfully browse to the desired folder if I wade through 'My Network' or 'Network Places', or whatever W7 calls it. I can't get to the drive by letter, even if I disconnect it and then perform a 'Connect Network Drive'; it doesn't appear under 'My Computer' in this dialog box.

Any s-u-g-g-e-s-t-i-o-n-s?

Stupid question: Can you browse through your Home?

by seanferd In reply to W7 "Browse for Folder" do ...

That is, can you see your symlinked home directory in the explorer tree, either as a top level directory under Desktop, or through the C:\Users\Palmetto directory? (I'm not sure how this is represented when your profile is on a network drive in an AD domain.)

Are you starting this through RunAs admin?

The Homegroup functionality is turned off on 7, is it? I've heard this can cause issues in domain networks.

I can see my home directory as I: in Explorer under Desktop \ My Computer. I can reach I: through every other file access dialog box (Open, Save, Save As, etc.).

No, I hadn't thought of 'Run As Admin'. I'm logged on as a domain admin and in the 'Local Admins' group, but we both know that sometimes you've got to 'Run as' anyway. I'll try that.

We have Homegroup features disabled in our drive images and by group policy.

'Run as Admin' on Device Manager wasn't enough by itself. The key was Slayer's reminder that UAC's elevated account runs under a separate process and doesn't have my home drive.

Yeah, I saw that he mentioned this, and your reply. Nothing but your OP was here when I posted, and of course, my post wasn't even here after I posted.

I think we're in for some really stupid conversations of this site behavior continues with the Flying Dutchman posts.

The installer may not allow you to browse to the network

by markp24 In reply to W7 "Browse for Folder" do ...

Hi, if you updating a network card drive, i suggest you copy it down to the local hard drive.
To update it over the network may be a problematic method.
your card has to uninstall itself, then get the new driver inplace, logically this means it cannot access the network to get the updated driver, if the card is disabled in the process.

I'm not upgrading the network card. I can browse to other network drives, just not one particular one.

Did you have to answer a UAC prompt?

by Slayer_ In reply to W7 "Browse for Folder" do ...

UAC elevation runs as a different user and won't have your drive mappings. You can actually map drives as a UAC user, just launch a dos window using run as administrator and enter your drive map commands.

There's an interesting thought.

Well, smack me 'til I cry and call me 'Nancy'!

MMC (and Device Manager, by extension) must run as the elevated UAC account. As you noted, since it isn't the account I log on with, it doesn't get my home drive. I launching a command windows as Admin and mapped the drive. (The fact that I could map the drive without conflict confirmed it wasn't already mapped for that process.) I then started Device Manager from the command line ('mmc devmgmt.msc') and life was good.
