Re: Weird n0tworking issue
are you being blacklisted for sending too much data to the server, maybe its thinks you are DDoSing it?

I don't think so, as the hosting company have looked into it and said that it must be an issue our end. Also it would affect all the office computers if that was the case as we only have one external facing IP address.
Releasing and renewing the IP seems to be what does the trick. Though, sometimes you have to do it several times. With the MAC address changer program it tends to work immediately.
We're only doing normal ftp stuff although I have to admit that that can involve a rather a large amount of data. The CMS updating side is not all that intensive with just textual updating being done usually, although with some uploading of images and, infrequently, other media related files.
Thanks for asking the question though. The more that are asked the more chance that I might actually be able to track down the issue.
Re: Weird n0tworking issue
Pfff, really not sure about this one.
I used to get intermittent connectivity issues when the MTU was set too large on my NIC (had to lower it to something less than 1500).
Not sure this is quite the same scenario, though.

Hmmm, that doesn't seem to fit either and as far as I know it seems that MTU is set to 1500 which is a fairly default setting.
We would also experience it more generally, across the whole office of computers, I would have thought, and it would not be fixed by renewing the IP lease.
I also think that the one Vista machine we have in the office doesn't experience any issues (all other machines are XP32 with latest SPs and updates). I know Vista does networking differently which might provide some clues.
Re: Weird n0tworking issue
A fair assumption, and an interesting observation about the Vista thing.
Do all the machines have the same NIC? Perhaps it's something going on in the driver? Might be worth having a play.

There is quite a varied mix of machines, with different motherboards for different generations of processors (AXP, A64, early C2D and C2Qs). I'll look into what drivers are used and what iNIC chips they are using. May just be, but one is an HP machine and I'm fairly sure that wont have an embedded realtek chip in it.

i cam across a situation once where a whole heap of compaq laptops were dlivered to a clients site and they ALL had the same MAC address. Might it be a MAC issue?
Re: Weird n0tworking issue
DHCP lease expiring? If that happens and your IP changes it would break the connection. This would also explain the intermittantness of the problem.
As an aside you've turned off DHCP on your WGR614v7 right?
It's fairly bad practice to go around changing MAC addresses.
Re: Weird n0tworking issue
What's the OS on the web server? And how do you get to it (on the LAN, across the internet)? If internet, what router do you use to get out? If not on LAN, can you get a computer on the same LAN as the server and then try the transfer? If you can RDP to the server, can you try pulling the data on to the server, rather than pushing it from your end?

Hmmm, I'm erring towards it not being, as I've checked and they all seem to be individual, even though technitium seems to do the job more effectively.

Hmmmm, this might be something to investigate in regard to the networking equipment we don't have access to. Also it seems to happen quite regularly at 3pm so I think you're right, this might be the issue.
Yes, the DHCP was turned off in the WGR614v7 router by the guy that configured it. Why did you ask? Is there a known issue with this router version?
:S Yeah, MAC spoofing isn't good but it was the only solution that was working reliably.

Os is Server 2003 64bit.
The server is hosted at a remote location to the office, we have five such servers although all the other servers are 32bit versions; hmmmmm.
I can't say how we connect to the internet as I don't have access to the building's comms room. Might see if that can be changed though; I need to know more.
Can't get a computer on the same LAN as the server, it is hosted after all.
We do RDP to the server however they're locked down and unlocking them to allow them to ftp up the data, and sorting out the ftp at this end, would be a nightmare including getting the connection through the building's firewall and switch system :confused: to which I have no access :O_o1:
