Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information on how to do this, view the "Restoring
the Registry" online Help topic in Regedit.exe or the "Restoring a Registry
Key" online Help topic in Regedt32.exe.
SYMPTOMS
There is an error in the documentation of the NetBIOS cachetimout registry
entry. In both the TCP/IP Implementation Details Version 2.0 white paper
and the Windows NT Resource Kit, the low end of the valid range is
documented as being in decimal and the high end of the range is documented
in hex, as seen below:
CacheTimeout
Key: Netbt\Parameters
Value Type: REG_DWORD - Time in milliseconds
Valid Range: 60000 to 0xFFFFFFFF
Default: 0x927c0 ( 600000 milliseconds = 10 minutes)
Description: This value determines the time interval that names are
cached in the remote name table.
RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys And
Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and
Delete Information in the Registry" and "Edit Registry Data" online Help
topics in Regedt32.exe. Note that you should back up the registry before
you edit it.
The correct entry should look like:
CacheTimeout
Key: Netbt\Parameters
Value Type: REG_DWORD - Time in milliseconds
Valid Range: 0xEA60 to 0xFFFFFFFF
Default: 0x927c0 ( 600000 milliseconds = 10 minutes)
Description: This value determines the time interval that names are
cached in the remote name table.
