Dear All,

I have a situation where there are 2 offices linked by broadband. I need to check the bandwidth but would expect it to be between 1 and 8 mb. I need to install a windows based 2 tier DB app. such that users on both sites can access it. What would be the best architecture....?

Options that I can think of include:

1) Remote Desktop into the server with a specific client user name, and then access client s/w
2) Install Client s/w locally and have Server s/w on Server...

Do you have a view on something completely different like the use of web technology.

Someone has advised me that there are issues with Terminal Services and use on Broadband in that it can drop you incorrectly, and by the time you have relogged on a number of times you start to run out of CALs, as well as corrupt DBs. I have not experienced this I must add.

Views very welcome.

    It depends on the number of users and the type of DB app.  In many cases you can just link the two offices via a pair of VPN routers.  These can be cheap linksys routers or higher end SonicWalls or Cisco's.  If the DB queries are efficient it may be quite possible to just have the users run locally.  If there is a larger number of users or the application is not well optimized, I would consider Terminal Services.  Terminal Services will have no issues that Remote Desktop doesn't have as they are essentially the same technology.  As for relogged on users, TS licenses are per-user or per-device.  Just choose the appropriate.  Additionally you can specifiy that disconnected sessions remain open allowing a user to re-connnect to the same session or automatically close allowing a new session to be freed up.

    Corrupt DB's is not a factor with TS, but could be with a poorly connected VPN, but usually that would be quite rare.

    If you are running a database program you problay wont get good results with a vpn. Try it and see, but you may have to end up using terminal server.

    If you have a 10mb link between the offices you should be fine. Rember dsl is generaly fast downstreem and slow upstreem. Upstreem is needed at the site that has the db server. So if you have dsl at the db site you wont be seeing fast speeds.

    Thanks for the comments..... Actually it is a 1 or 2MB ADSL link between te offices. So, from your comments it seems that Terminal Services may well be the answer. Do I assume that you setup seperate users on the server and then let the clients login via Remote Desktop using seperate user logins. Then within that virtual client on the server, one would access the client application which would then link to the DB on the same server.

    Thanks again,

    no you use AD and allow them to login to the terminal server. You need to buy and activate TS lisences.
