When you have multiple segments, you may not be able to see resources on other segments, if W95 and/or WFW clients are present?
This problem is symptomatic of W95 and WFW clients winning the browser elections.
Disable browse list maintenance on your W95 and WFW clients and use an LMHOSTS file on these clients to define the PDC and domain:
1. For W95, set HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VNETSUP\MaintainServerList to 0 and HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VNETSUP\Ndi\Params\MaintainServerList to 0.
2. On WFW, add MaintainServerList=no to the \[network\] section of System.ini.
3. Edit the LMHOSTS file on these clients and add:
<IP Address of PDC> <PDC Name> #PRE #DOM:<Domain Name>
<IP Address of PDC> "<Domain Name> \0x1b" #PRE
where the text within the quotes (") is exactly 20 characters.
4. For WinNT based computers, make sure that the WINS Client (TCP/IP) protocol is at the top of the binding order at Control Panel / Network / Bindings / all Services for the Server and Workstation services.
5. For W95 and WFW clients, TCP/IP must be the default protocol.
6. For WFW, be sure to use the updated WFW files from the Clients folder of the NT Server CD-ROM.
