It is OK to have mixed case names in the WINS database, as the NetBIOS name space is NOT case sensitive.
If you have a computer named Server1, you could see:
SeRvEr1---- \[00h\] SeRvEr1---- \[02h\] SeRvEr1---i \[00h\] SeRvEr1---i \[02h\]You might also see entries similar to:
iNtEl.nBcBaGr. \[02h\] iNtEl.nBcBaGr. \[00h\] iNtEl.nBcBaGr. \[01h\]These name registrations are made by the Intel Ping Discover Service ( PDS) software from the Intel LanDesk Management Suite.
