I found this on Technet for you. I think you will like it!
When you logon to Windows NT using cached logon information, if the domain
controller is unavailable to validate you account, you are unable to access
network resources that require domain validation. However, you are able to
access network resources that do not require domain validation.
Through the registry and a resource kit utility (Regkey.exe), you are able to
change the number of previous logon attempts that a server will cache. By
default, Windows NT will remember the 10 most recent logon attempts. The valid
range of values for this parameter is 0 to 50. A value of 0 disables logon
caching and any value above 50 will only cache 50 logon attempts.
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.
Cached logon information is controlled by the following key:
HKLM\Software\Microsoft\Windows NT\Current Version\Winlogon\
ValueName: CachedLogonsCount
Data Type: REG_SZ
Values: 0 - 50
Any changes you make to this key require that you restart the computer for the
changes to take effect.
