I am currently experiencing Delayed Write Failed errors when saing reasonable large files over a network share. I have googled a lot and tried several things including: Disabling write cache on host drives Updating NIC drivers Forcing both NICs and the switch to the same network speed and nothing seems to work. The error log has Event ID 50, soure MRxSmb and the data ends c000020c (some solutions are for an error ending c000022c). For some reason the problem seems worse since the machine joined the domain, as opposed to being a workgroup PC - not sure if it is related. I have checked all permissions etc. Any help would be really appreciated, I just can't find a solution anywhere.

Thanks for the link but I have worked through all of those suggested solutions with no luck.

I have just tried dragging and dropping a file onto the network share (as opposed to saving from an application) and although this time it copied fine it took several minutes for a 30Mb which is an incredibly long time, so there seems to be a general speed issue too.

Even at 100 Mbps, 30 Mb's of data shouldn't take more than a few seconds to copy by dragging and dropping. Something is definately up with your network but with zero information on your network setup, helping you troubleshoot the issue is going to be a slow painful process. So, if you want some help, give us some details on your setup. - Number of clients - Number and type of devices between the two clients you're copying from/to - Type of software you're saving from and where does the data get saved to (when trying to save from the software itself as compared to dragging and dropping files) - What speed NIC's, switch, router etc? - What are you showing for connection rate with all connected client devices - How is your network setup (ie: internet >> SOHO router >> switch >> clients)

We have in excess of approximately 15/18 PCs running Windows XP SP2 connectes via a Netgear switch to a Windows 2003 server. The switch is connected to the internet via a linksys router. All PCs are workgrouped except for one, which is running as a client to a domain on the same server sharing the same resources, on which this issue occurs. This is a 'test' PC as I want to move all onto the domain the the new year. We run a variety of software - I noticed the issue when trying to save an image from photoshop onto one of the server's shared drives. Nobody else has had this issue on their workgrouped PCs, saving the same sort of documents on the same drive. The PC in question is set up as a domain administrator and has full access to the domain. If there is anything else I have missed please let me know, and thank you for having a look at this problem, I can't find anyway around it.

Have you tested the network cable? If it is faulty, it could be the source of the problem. Use a packet sniffer such as wireshark to capture the network traffic during the file transfer and see if there is any out of the ordinary traffic, such as large amounts of retransmissions. http://www.wireshark.org/download.html
