Extremely wierd problems with Windows Networking

[StricJux]

I have a preety standard home networking setup: 3 pc (2x WinXP, 1x Win2k), 1 notebook (WinXP) interconected like this

3 x pc ---via ethernet100---->Dlink 614+ router
1 x notebook ---via WiFi------>Dlink 614+ router

Currrently all computers (including notebook) have working TCPIP (ie, they can ping each other and have access to the web). All of them have enabled NetBios over TCPIP. The all pcs connected can browse each other's files (the usernames and passwords are the same on all four computers).

UNTIL! :Q
The laptop somehow lost the rights to browse the local workgroup. When trying to connect, the laptop simply shows a "no access to the workgroup" alert. Other three computers siting on the network acctually see it (ie. when you open workgroup "HOME" you see the laptop icon) but cannot conect to any of its shares.
All four computers have the same settings, i have no idea what could have gone wrong. Dammit, this windows networking is getting more funky every day. Shure hope, that in longhorn they will do something with this wierd network problems.

This is weird since you're indicating you didn't change any settings. You had to have done SOMETHING to break it. Windows networking is used in mission-critical environments and just doesn't stop working correctly on its own. Double check everything and post and further findings back here - I'll try to help.

does the laptop have a pcmcia wireless card? is it correctly installed? does it show up as working properly in the hardware configuration?

i know you may have checked that 100 times, but every time my laptop has a problem on the network, its the damn ethernet adapter dongle or the pcmcia card not all the way in or something annoying like that.

I hate to ask the obvious, but did you try shutting down all the computers and the router, then bringing it all back up?
