Word documents over WAN Links

I have an isue that has not changed much as our internet links have been upgrade over the past few years. They are now at 512KBps up and down. We have been getting our users to work on and save their word, excel and other documents from our server location over the WAN links. Most of these documents are quite small, 50KB. The users say that most of the time even though the document can open quite quickly, after some time, it can get a very long timer symbol while saving and sometimes the whole program will error and then shutdown not having saved the cahnges.

This seems to be an isse related to connectivity rather. It is not an application problem. It seems that some kind of issue  is being experienced with the software operating over the WAN link. Is there any direction someone can point me towards to ascertain why these issues are experienced.

What kind of communication process is used by word to save/transfer data?

Currently all division users store their data locally and are responsible for backup....not good as they are not strict on carrying this out.

why dont you have the users save their docs to a central repository locally and maybe configure a DFS kinda setup to replicate over to the remote site..
If you have Win2k3 Server R2.. you can look at this..

How are users accessing word documents over WAN? Are these 2 sites connected by a VPN or maybe the user connecting to the office VPN?

One thing to keep in mind is that Word uses tmp files to temporarily store changes. After closing a document it usually tries to delete the tmp files becuase they are no longer needed which can be slow if the user does not have permission to delete files in the folder. Do the users have the necessary permission in the folder to delete files?

Our network is set up as as a  private IP Network with our ISP, they are not using a VPN connection.

There should not be any permissions issues. They do not experience issues when saving on local machine and the directory they are working with has their persissions enabled on them.

When you say "the directory they are working with has their persissions enabled on them." does that include modify permissions?

Also make sure the latest service pack for MS Office and windows is installed.
To get a realy detailed look at how the file is being, read, and saved on the server end you can try to run procmon which is a utility provided by microsofts sysinternals. http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx

The only other thing i can think of is maybe antivirus scanning the file activity.

This seems to be issues related to TCP/IP implementation which have been improved in Win 2008/Vista. There is a document 'Next Generation TCP/IP Stack in Windows Vista and Windows Server 2008' related to this here:http://technet.microsoft.com/en-us/network/bb545475.aspx

It is something we will have to test in the future.
