According to Microsoft, you can't.
You need to format and reinstall.
At least that's what the MCP exam teaches you !
If you need to get data off this machine, copy it all to another server, or create a spare extended FAT partition and copy it to there, then install NT 4 and move the data back, or leave it there.  Whatever !

Sorrie,Tim you can do it. Convert it to NTFS in Windows 3.51... but this works only if you have SP5 from 3.51. The convert.exe that is in that SP does convert from HPFS to NTFS.

The information in this article applies to:
 
 - Microsoft Windows NT operating system version 3.1
 - Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS
========
 
When you instruct Windows NT Setup to convert an HPFS volume to NTFS or use the
CONVERT command at the command line, the file system conversion fails and the
following error message appears:
 
   The conversion failed. The [drive] was not converted to NTFS.


PS I have done it, so I know that it's works.

When you have NT 3.51 it is the same. If you still want to use HPFS under NT 4 that is possible.

Simply copy the redirector pinball.sys to the system 32 folder in winnt 4 and than look at the entries in your NT 3.51 registry.

But isn't this a command  <diskdrive>: /FS:NTFS used  to convert FAT to NTFS.  Or it is the same command used to convert FAT and HPFS to NTFS.

No you can choose let's say you want format the C-drive, you can use
convert c: /FS:FAT to format to Fat
convert c: /FS:HPFS to format to HPFS (Only if you have Windows NT 3.51).
convert c: /FS:NTFS to format to NTFS
