Suspicious file (AdWare? Virus?) named NETBIOS.dll

Is this something put into Windows by Spyware? Found it in "32-Bit Modules loaded" part of System Information.
:
NETBIOS.dll ... C:\Windows\System\NetBios.dll
:
There is NO manufacturer's name, NO Version number.
:
File is dated 4/23/99

The date looks suspicious .... if this is a virus, or Spyware, could it have been backdated to make it appear as if it'd been part of Windows for a long time so as to avoid suspicion by user's.

 

It does look suspicious. It is, however, installed as a part of windows. It's in the cabs. I have Win98SE and it is here:
Win98_38.cab

 

Hi Gary R,

4-23-99 is the date that the OS was installed.

Betcha' got an eMachine....

Its not in any way a virus, trojan or spyware file.

Its a component of Windows networking.
