I am about to pull out whatever hair I have left…
I have a single LAN with Windows, Linux and Mac machines, with one standalone Ubuntu fileserver (using Samba) and webserver hosting several intranet websites.
Everything works perfectly with Mac & Linux, but mostly non-connectivity from all Windows PCs (XP Home, XP Pro & 7) – there seems to be no rhyme or reason.
Check this out:
1) All IPs are static and have internet connectivity.
2) I can successfully ping (both name & IP) all PCs and the server from all the Macs, Linux, and from the server.
3) I can successfully ping (both name & IP) all the Macs and Linux machines from all the PCs.
4) I can successfully ping (both name & IP) all the PCs from all the other PCs
5) But I cannot ping the Ubuntu Server from any PC except…….
…….I did the following testing from several PCs:
200 pings of 32 bytes to the server:
Results:
The first 188 pings timed out.
The last 12 replied.
time to reply – 3263ms for the first one, two at 1ms, one at 250ms, and the other 8 at 1ms.
Then I pinged 50 – all replied, and I connected to server shares and intranet websites.
Went to get a cup of coffee.
Connection gone.
Pinged 50 – all timed out.
Went to bathroom.
Pinged 50 – timed out except last 6 pings.
Trick is, during this whole day, the Macs and Linux machines never lost connection with the server…
Does anyone have an idea, or should I be talking to Rod Serling?
I’ll be gone for the weekend to recuperate – will touch base here Monday.
Thanks much in advance.
