MS Office 2003 applications open very slow across WAN link

Posted on 2006-04-25

I have customers that want to open files that are sitting on a file server across a WAN link (DS3).  Whether double clicking to open the file from the network share or opening the application first and then opening it from within it is very slow.  Copying the file down to the local workstation and then opening works fine.  A couple of questions:  
1. Is there anything that can speed this up or is it inherent with office applications over WAN?
2.  Is there documentation, white paper etc... that states what the expected functionality is when opening files over a WAN?

Of course the larger the files, the slower it is!  Of course we all want the customer to be happy, but there has to be a limit.

    Thanks for the tips, I am definitely interested in the mapped drive article.  Our users have several mapped drives that are in a persistent state.  I think my first test will be to disconnect all mapped drives and then create a shortcut to the share to see if this have any affect.

    Thanks again,

    You can also try caching using "offline files" :

    Would work, however, the files are shared.  I'll definitely recommend this for situations where only one person accesses a file.  Thanks.
