Ok here goes,
I have two computers in a simple peer-to-peer; Desktop and Laptop, Desktop dual boots between Windows 2000 (yeah!) and Windows XP Professional (boo!), Laptop only has Windows XP Professional (boo!). Before that both Desktop and Laptop ran Windows NT 4.0, no problems with my home network, upgraded both to Windows 2000, again no problems with my home network.
Both Desktop and Laptop have Intel PRO/100+ Management Adapter NICs, they then connect to a Intel InBusiness 8-Port 10/100 Switch, there is also an Intel InBusiness Print Station.
When Desktop is running Windows 2000, both Desktop and Laptop can ping the IP address of each other and ping the name of each other. Both can also see the shares on each other and Network/Computers Near Me can see both Desktop, Laptop and the Print Server. Both can print to the Print Server also.
However, I was told that everything in Windows XP would be simple! When both Desktop and Laptop are running Windows XP, Desktop can ping Laptops IP address and Laptops Name but cannot use any shares. Laptop cannot ping Desktops IP address or Desktops Name or use any shares. But both can print to the printer on the Print Server!
To summarise...
IP Address for both Win2K and WinXP
Desktop = 192.168.0.1 (255.255.255.0)
Laptop = 192.168.0.2 (255.255.255.0)
Print Server = 192.168.0.8 (255.255.255.0)
Ping IP Address from Win2K
Desktop Win2K -> Laptop WinXP = OK
Laptop WinXP -> Desktop Win2K = OK
Ping Name from Win2K
Desktop Win2K -> Laptop WinXP = OK
Laptop WinXP -> Desktop Win2K = OK
Use Shares from Win2K
Desktop Win2K -> Laptop WinXP = OK
Laptop WinXP -> Desktop Win2K = OK
Ping IP Address from WinXP
Desktop WinXP -> Laptop WinXP = OK
Laptop WinXP -> Desktop WinXP = NOT OK
Ping Name from WinXP
Desktop WinXP -> Lapto WinXP = OK
Laptop WinXP -> Desktop WinXP = NOT OK
Use Shares from WinXP
Desktop WinXP -> Laptop WinXP = NOT OK
Laptop WinXP -> Desktop WinXP = NOT OK
Both Windows 2000 and Windows XP have the following:
[*]Clients for Microsoft Networks
[*]File and Printer Sharing for Microsoft Networks
[*]NetBEUI Protocol
[*]Internet Protocol (TCP/IP)
[*]QoS Packet Scheduler - (Windows XP only)
[/list:u]
The NetBEUI protocol is used for the InBusiness Print Server, I'm not doing any fancy IP Security or Filtering.
Both computers have the same user, me, logging on with the same password for both computers and both operating systems.
With Windows XP, I have tried double clicking Network, then selecting Set up a home or small office network, I have followed the instructions and everything appears to be OK.
I'm lost as to why Desktop Windows XP cannot see Laptop Windows XP and vice versa, but Desktop Windows 2000 can see Laptop Windows XP and vice versa.
Anybody have any clues?
