Resolved Trouble accessing docs on lan

Ok…Here’s the scene……

4 computers on network, Linksys wireless router, just sharing Docs folders

PC 1….Win2K SP4 all updated patches
PC 2….WinXP SP3 all updated
PC 3….WinXP SP3 all updated (Laptop)
PC 4….WinXP SP3 all updated

PC 1 Can see and access docs on PC’s 2,3, and 4
PC 2 Can see and access docs on PC’s 1,3 Can't see or access docs on PC 4
PC 3 Can see and access docs on PC’s 1,2 Can't see or access docs on PC 4
PC 4 Can see and access docs on PC’s 1,2, and 3

PC 1 is connected to router via Ethernet
PC 2,3,4 are all connected thru wireless

What am I missing? Why can’t PC’s 2,3 see or access PC 4?

Any help appreciated

Thanks in advance

 

Firewall settings, either on the router or a software firewall on PC4?

 

Are Jeez...checked the FW on PC4. never gave the router a thought...will check it on Monday or Tues and let you know...thanks for the quick reply

 

Thanks for the reply Tony...those things are all set properly

 

Are the user names & passwords on each computer same or different ?

 

thanks for the help guys ..it was a Firewall problem.
