[Windows] Network drive - Unexpected error - path is on mount ...

Hi, I work on Windows in corporate environment on network drive, so my working directory in explorer looks like: Home (\aaa.bbb.ccc.net\UserData\User1) (P:) In conda prompt it look like ordinary P: folder. I create folder like test_DVC. In this folder: git init, dvc init works fine, but when I do dvc add somefile.txt, I get: ERROR: Unexpected error - path is on mount '\\\\aaa.bbb.ccc.net\\UserData, start on ‘\\\\AD3AB.AAA.BBB.CCC.NET\\UserData’ I’ve tried also: dvc add P:\test_DVC\somefile.txt, I get: ERROR: Output(s) outside of DVC project: P:\test_DVC\somefile.txt I’ve also tried without git, by dvc init --no-scm but result is the same

DVC version: 2.11.0 Is it expected and I miss something obvious, or bug?

@mglowacki100 are you able to try changing your mapped network drive so that you mount \\AD3AB.AAA.BBB.CCC.NET\... (instead of the shortened \\AAA.BBB.CCC.net\...)? It looks like your network/system may configured so that the shorter hostname is always resolved into the full AD3... hostname in UNC paths, which causes issues when DVC tries to compare the two

@a-orn It was some time ago , but IIRC:

1. You need to add drive with full path, beware that “hidden parts” like to change from time to time by sys admins and this fix stop to work, (update of full drive path is required). Let’s call this new drive N:
2. In command line you need to change drive without hidden parts to N
3. next create test dir: mkdir dvc_test, cd dvc_test, git init
4. now dvc init probably will fail (dvc is not recognized as internal or external command…). You need to locate dvc.exe, if you installed it with conda it should be in conda folder …\envs\your_env\Scripts\dvc.exe, so you can run this as absolute path C:.…\dvc.exe init or make a shortcut
5. now dvc add sample_file.txt should work (shortcut version)

If you’ve this basic test configuration up and running, then check your specific case. Hope this helps.
