8 |
Description
Specifies the operation code that NetBIOS over TCP/IP (NetBT) uses in name refresh packets.
The Microsoft implementation of NetBT uses a default of 8; however, other implementations, such as Ungermann-Bass, use a default of 9. Interoperation of clients and servers depends on them using the same operation code. If the default operation code (8) is incompatible with other systems on your network, then add this entry and set the value to 9.
This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
Activation Method
If this interface is configured by DHCP, then a change in parameters will take effect if you enter the command ipconfig /renew at the command line. Otherwise, you must restart the computer for a change to take effect.
