Mapped Network Drive accessible, just not from Windows Explorer

Hi All

I am on a Work Network at work, windows 7 PC on a windows domain

I have a mapped network drive called \\persr11. Now it is mapped to the drive letter F:. Now the problem is that when I try to access the drive from Windows Explorer(Computer), it says: "F:\ is not accessible. Device is not ready."

However, when I access it from the search bar like this: \\persr11, it goes into the drive, all fine.

How do I remap the network drive to the letter F to access it? Prefereble Command Prompt please. I tried the following command but it did not work, not for F: and not for any other letter:

net use f: /persistent:yes \persr11

If you go to command prompt, or make a batch file this will work. Make sure right after the \\SERVERNAME\Directory
net use f: \\persr11\DIRECTORY /user:LOGIN_NAME PASSWORD

Thank you 1pcman, it works
