>>you meanthe connection string from asp to the query right
yes, because if you're using sql2005 management studio, you're logging into the db servers with either your windows username/password (in which case the app is not using the same) or a username/password that exists in the db servers (which should be part of your app's conn string)...
>>but im using windows authentication so im logging into the app with my network password
That gets you into the application, but unless you are using impersonation, the app is still using the default account NETWORK SERVICE (IIS6), if lower version of IIS, it's using the account ASPNET.
So when the app communicates with other servers (like the DB server) it is using one of those accounts.
Usually what I do, is create a user on the DB server(s) called "webapps" and then any connection string a web app(s) uses, I use the username and password for the "webapps" db account.
What connectionstring do you have currently?
ok i actually am using impersonation actually. do u use windows authentication? or forms when you create your webapps person? cuz im using windows auth.
can u show me an example of the syntax u use for your conn string?
all i did for my connection string was use gridview and bind the query(view) using the same connection string i set for the rest of the tables and in the web config. of course these others are not using a linked server.
this is what my web config looks like
<connectionStrings>
<add name="TestADNIConnectionSt
providerName="System.Data.
</connectionStrings>
<system.web>
<roleManager enabled="false" />
<identity impersonate="true"/>
<customErrors mode="Off"/>
<compilation debug="true"/>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Windows"/>
<authorization>
<allow roles="ADS\In-mmge-hd-admi
<allow roles="ADS\In-mmge-hd-user
<deny users="*"/>
</authorization>

I don't think the problem is because you're using a linked server, it's a problem with the connection string, does your connection string include a username/password with access to the db server?
