Hi,

I hope there are no other topics covering this problem that I am having as
I don't want to waste anyone's time by posting it again.

Anyway here's my problem.

I have two PCs connected via an CNET 8-port switch using to cat5e Both the nics are working and the settings for each nic in the control panel-->System--Devices
appear to be correct, I can connect from PC A to Pc B and access its' files and resources however I can not Connect from PC B to PC A and share its resources.
My Ip settings for PC A are
IP: 192.168.0.1
subnet mask 255.255.255.0
Gateway:0.0.0.0

My settings for Pc B are

IP: 192.168.0.2
subnet mask 255.255.255.0
Gateway: 0.0.0.0

All antivirus software and Firewalls are off when I connect the two systems.

I have tried pinging PC A but the Ping command just shows Pinging 192.168.0.1
and then nothing after, no time-outs, nothing.

Suprisingly when I connect the two systems via a crossover cable I am able to access PC A from PC B however this is not suitable as my sister also wants to connect her PC to the LAN.

Thanks in advance :tazz:

did you set both machines up for being in a workgroup? did you enable the file and print sharing on both machines?

Hi dsenette,

Thanks for the reply,

I did set up printer and file sharing on both computers, both belong to the same
workgroup and I have also tried using 6 different patch cables all cat5e but i still get the same problem.

Both nics are currently set to auto-negotiate but I tried all the various other options from 10BaseT half-duplex to 100BaseTx full duplex as well as turning flow control on and off (rebooting each time).

Another thing which I neglected to mention which could be extremely important to my problem(I don't know) is that my brother's PC (PC A) has Visual Studio installed on it, but he said he did not set up anything that requires password authentication
or anything else that would block PC B.

I also tried booting into safe mode with networking but with no luck.

I also took the switch back to the shop where they tested it in front of me and it is in working order.

If you connect with a crossover cable and everything works the problem has to be in the switch, did you try switching the plugs to different ports, is it a new switch? If not, it may have been configured to filter certain ports

Hi,

I tried all the ports and yes it is a new switch, it was tested at the store and the LAN connection works both ways. How would I check if the switch filters certain ports though as the manual I received was less than thorough.

thanks

Well, I know with cisco switches you can telnet or hyperterminal to, to configure. Some switches you can use http to configure, i dont know about cnet switches. it varies from one manufacturer to another. does your switch have an ip address, if so put the ip in your web browser, http://ip address

As far as I Know the switch does not have an ip address and now I'm getting a message that says "Mshome is not accessible, you might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permission" when I try clicking on view workgroup computers. But like I said before when I connect direct(crossover cable) everything works. :tazz:

I have also tried the various NET commands i.e NET add, net send ie from both pcs
and again only PC A can remove or add PC B on the network, PC B NET command just hangs.

Thanks for being patient

Both systems belong to the same workgroup and double checked that the firewalls
are off.

Every network service is running except for the DDE, DSDM and remote access.
I am completely stumped and I don't want to waste any more of your time, so tomorrow I am going buy an LG switch and hope that it works or else I'll be posting
the same topic only with with a different switch, LOL.

Anyway thanks for all the help.

If I manage to figure out the problem I will be sure to post the solution here for
anyone else who might be experiencing it. :tazz:
