If this is on a VOIP system, this could be it. This one caused me undue grief for a number of hours troubleshooting until I got to the bottom of it. It was the SIP "ALG" service in my router. I had to disable it. I found out after I had already tried another router, like you. Before I disabled it, I could do a continuous ping and get back something like... ping... no response <delay of 5 seconds or so> one response no response no response no response no response response! <delay of 3 seconds> no response response! response! response! no response no response no response <delay of 10 seconds> response! no response etcetera... ....was driving me crazy... Turned out what I had to do was to disable ALG support in the router (Netgear in my case). Check out this link... http://www.voip-info.org/wiki/view/Routers+SIP+ALG Anyway, other than that, I'm out of ideas, considering what you have already changed. -Frank "Don" <donald7.44(a)gmail.com> wrote in message news:eWRJqO1uKHA.3896(a)TK2MSFTNGP02.phx.gbl... > Hello, around last month we started to lose lan connections to our NAS.

However I am changing every network card in the systems and seeing if that works. Right now all machines have a static ip and are connected to a switch with no router and seeing if any thing drops. every machine is also being tested one at a time connected to the switch and NAS with a large data file being transferred to see if it causes any problems.

Ok it turned out 3 network cards were bad, one router had massive packet loss, and one network cable needed to be replaced. After all that was fixed systems ran great until... the receptionists computer decided to die and it sent a surge through the network killing off everything that was fixed. Replaced everything again switch survived and they are now up. |
