This one has not only stumped me, but our company's entire IT department...
I work remotely 100% now(previously I only worked remote occasionally). Our IT department has a VPN setup for all of us, and I can connect fine from my work-issued Win-7 Pro laptop.
On-site at our main office, I also have a remote PC setup that only I use(single-user Win-7 Pro). My username/password are the same for my local PC here, the VPN, and my remote PC(which is on-site in our office...yeah, that sounds a bit confusing now that I type it out).
Several weeks ago I started having a problem from my laptop(here with me) that intermittently I could no longer access all the folders on a network share(in our main office). It was seemingly random, as one moment it worked and the next it didn't. It was not affected by disconnecting/reconnecting to our VPN. I did not install any Windows Updates, update any drivers, or anything else that may have had an undocumented effect on connectivity/permissions.
What seems most odd to me is that the mapped drive was: \[ServerName][Folder1][Folder2] under which I had access to about 50 folders, each with numerous subfolders/files. Now I only have access to one specific directory and its files: \[ServerName][Folder1][Folder2][Subfolder1][Subfolder2][Subfolder3][Subfolder4][Subfolder5][Subfolder6][Subfolder7][Files]
But here's where it gets really weird...while I'm still logged into the VPN I can remote into my PC in the main office - and I have access to all the directories/files that I've always had. So it doesn't appear to be a permissions/share issue, as I can access everything fine from my on-site PC when I connect remotely to it.
I've tried numerous suggestions, and disproven other possibilities. So far I've updated registry settings in 3 different keys, tried Net Use from an elevated command prompt to disconnect/reconnect the share, cleared settings in Credentials Manager, confirmed NetBIOS over TCP/IP is selected, and ensured Client for Microsoft Networks is installed and checked for all my network connections.
I've Googled it for hours, but most hits either relate to local networks/Homegroups, are related to XP and or Vista, result from a wireless router issue(FYI my laptop is wired in with CAT5e), or do not relate to the partial access issue I'm having. Has anyone here seen this, or recommend a good forum I could ask it on?
