first, this doesn’t make sense…you updated the routers? like IOS/firmware? just because you update the routers, that shouldn’t change how your roaming profile behaves. If you are downloading the mydocs as part of the profile now, weren’t you also doing it before the update? That’s just how the roaming profile works…you download it to a pc from the network. Is there something more that changed other than what your telling us?
Need to know the following: is there a local domain controller authenticating the users and hosting the profiles, or is the domain controller at a remote site? if at a remote site, are the profiles also stored there? (they should be stored on a local server.)
Ideally, you would have a domain controller at each remote site which hosts the profiles. this should minimize logon times. If you can’t do that, then point the profile path to a standalone local server/machine at each site and point to the remote DC for authentication.
If you have that setup but the profiles are too big to download quickly, then don’t store the mydocs as part of the profile!! make the target of mydocs a network drive, or another folder on the local machine that’s not in the profile. (that’s the easiest thing to do. always minimize the size of the profile).
If you are still having trouble and it is truly related to the upgrade of the routers (???) than it may be a timeout issue. We had a similar problem a couple years ago when setting up remote sites that connect to a DC over a slow WAN. There is a registry setting than can be manipulated to change how windows sends Domain authentication traffic over the network. we called hydra network for support and they emailed us the reg hack that we needed. we had spent 2 months troubleshooting the issue, and finally broke down and called them ($35/hr for phone support) and it was fixed in 2 hours. Please let me know more info or tell us how this gets resolved.
