For the last couple of months, my database keeps getting corrupt regularly. This typically happens when I download updated profiles or add new DVDs. I would get an error (which I wished I took a screenshot of). It will say about 2 fields that it has an invalid value "[ ]". Most of the times I can repair the database, although it seems to delete records. Recently it turned into quite a mess where several profiles were gone. I had to go look at my online database to compare one by one which ones were gone .

These issues started a while ago when I would also get a Windows warning stating "Delayed Write Failed". Which brings me to some background info...

I'm not sure if this is causing this, but I have a particular deployment. My entire database is on a file server as a shared directory, such that I can access my database from mulitple clients (desktop, laptop, netbook). This worked great for years though. But the fact that the latest DVDP now also has a sharing feature made me doubt. I don't understand the advantage of that sharing feature though as you can't even update your database from the clients, whereas in my setup any client could do the update. Mind you, I make sure that no 2 clients are accessing the database in parallel, as I realize that that might corrupt the database.

I'm at the point now that I've installed DVDP on my file server (XP Pro) and only do updates of DVDP anymore through Remote Desktop on the file server itself. This of course I would like to get fixed still, because I also use DVDP Mobile which is synced to my desktop so I can't keep using the desktop client in read-only mode.

Here's a link to look into to see if you can find and solve the underlying issue for the network delayed write errors.

You can also try some long pings.
From a cmd prompt:

ping -t -n 2000 -l 60000 x.x.x.x

Where x.x.x.x is the other's IP

Do this on both PC's simultaniously towards each other.
Let it run for a minute or so and press Ctrl-C .
Check if there is any loss.

Thanks for the suggestions.

Well, I recently had to re-install my file server completely and since then haven't seen the 'Delayed Write Failure' thing anymore. Nonetheless, I am still getting the DVDP errors. In fact tonight again a problem. It now tells me that there is an error in my 'With Love From Russia' profile from my 007 box, and asked if I wanted to delete it. I said no, but it still is missing from my database now. No idea why this happened because I have not touched that profile in ages.

So I had to go restore from my file backup. I now have done the suggestion of starting from a completely new database and doing the DVDP Import into that. I hope that finally fixes it, because I'm getting completely clueless why I keep getting errors. Obviously I'll be doing the built-in DVDP backups regularly now (in addition to my standard weekly file server backups).

FWIW, the network setup is pretty standard. Server and Desktop PC connected through LAN on the router. Netbook and laptop connected through Wfi. The error tonight was on my Desktop PC.

I agree with the Dr.

The problem I am having is exactly what is described here : http://support.microsoft.com/kb/890352 . However, my server is XP Pro, not 2003, so doubt that the cause is the same.
After googling on that same event detail, I however found several hits of other people who have the same problem, even on XP. There are a few mentions about changing the network card's rate from 'auto' to '100 Full Duplex' so am trying that out now...

Update: no help, same problem during update of profiles .
