I have a shared computer. If I login with windows userA, I can run the following:
normalizePath("//mydrive/my/path", "/")
and it returns:
"\\\\mydrive/my/path"
However if login to windows under userB, I get this message:
Warning message: In normalizePath(path.expand(path), winslash, mustWork) : path[1]="//mydrive/my/path": An unexpected network error occurred
What does it mean? This has important consequences, as it prevents to add "//mydrive/my/path" to the .libPaths() when running under userB, e.g .libPaths(new="//mydrive/my/path"), it prints the same warning, then as soon as I try to use a package that is in this lib location, it show the ERROR:
Error in normalizePath(path.expand(path), winslash, mustWork) :
path[1]="//mydrive/my/path": An unexpected network error occurred
Here are the details of my session under userA:

Finally, I also noticed the following warning on userB, which could be linked to the same issue:
