If it takes too long to navigate to other network resources in the file Open/Save dialog boxes, it is generally a DNS issue. This is specially true on a Windows 2000 computer in a Windows NT domain, where DDNS is not yet implemented.
The problem is caused by the default Windows 2000 name resolution sequence, which is DNS and then WINS. The DNS lookup must fail before other methods of name resolution are attempted.
To resolve this problem:
1. Use tip 0187 » Where is my last Last Known Good?, to locate
the ControlSet that will be current at the next boot.
This is the value in the HKEY_LOCAL_MACHINE\System\Select\Default value name
(0x1 is ControlSet001, 0x2 is ControlSet002).
2. Use Regedt32 to navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet<From Step 1>\Services\Tcpip\Parameters
3. On the Edit menu, Add Value name DnsNbtLookupOrder, as a REG_DWORD data type. Set the data value as follows:
0 - This is the default setting and causes name resolution via DNS to be first.
1 - NetBT name resolution will be attempted before DNS.
4. Exit Regedt32.
5. Shutdown and restart.
NOTE: If you make these changes to the CurrentControlSet, you may experience a BSOD, Blue Screen Of Death.
