I have a basic workstation using w2000 with wired lan that currently is connected to the network and is sending data, however it cannot receive any for some unknown reason. A similiar thing has happened to a member of staff with a wireless laptop using xp.
could be xp firewall?
tried different network card in it etc

What data can it send? What data can't it receive?
Can you ping other workstations/servers from it? Can it be pinged from other workstations/servers?
Has it been assigned a correct IP address (using dhcp or statically)? Have you tried using IP addresses as well as host names (may be a problem with DNS)?
I've had similar problems in the past and I find that once I've checked all of the above I have usually found the break in the chain somewhere.
switch needs rebooting (or is on its way out?)
Also, try different network cables (in case the one thats being used is damaged). A cable with just one damaged wire can sometimes get limited connectivity and behave very oddly in my experience.
Tried everything but a new network card. However if I have to open up the machine to change it then I might as well put a CD drive in there and update the pc cos it could do with a fresh install which will hopefully solve the problem.
I have had this many times in several schools, the answer is usually a network cable/connection problem, or the network card itself (usually the port on the network card has a bent pin, stopping recv).
However, there has been several occasions where it was not the above. I found on one PC (NS Optimum pc with windows 2000), it would not receive. I tried everything known to man, including changing network cards, fixing windows playing with bios and so on.. nothing worked.
I ended up formatting the PC and putting XP on, which worked.
I did have a similar problem on another workstation which was caused by the upgrading of drivers. However this machine has been working fine and I have made no modifications to it in the past week before it spontaneously decided to start playing up.
Just waiting for OS to be installed now and see if its working normally.
Limited connectivity can be caused by:
Damaged cable/pin, wrong type of cable(cross over etc), network card driver not good, Network card is set as half duplex. In the wireless case not a very strong signal.
Check the above
The workstation worked fine after I reinstalled newer windows, but the laptop I mentioned is still having problems.
Its a wireless one and the teacher tells me that the wireless works fine at home, but as soon as it arrives in school it only sends and doesn't receive. Tried all sorts, apart from using a different network card which I think will be the answer as its currently using a 3-com one whereas we have d-link acces points.
You will be able to send but not receive if there is a problem with authentication. This could be wrong SSID, WEP key or wpa settings.Originally Posted by Pear
Cross vendor *should* be fine, but in the real world it generally causes issues! We have had problems with schools buying Netgear APs and D-Links NICs
I would always endeavour to keep the NIC and Access Point vendor the same.

Whenever I have problems with a wireless card I just uninstall it completely and then re-install it. Has worked almost EVERY time.
We use a range of NICs and APs and haven't had any problems (no serious ones anyway).
If your using XP SP2 I've found that the manufacturers bundled WiFi tools interfere. I generally uninstall them and let windows handle the connection.
If it is a Centrino or Intel 2300BG type chipset then you may be best disabling Wireless Zero Configration and using Intels own management software. The 2200 series don't like some other manufaturers basestations.
