On Windows Server 2003 R2 SE SP2 I am able to set Callback Options for a user on the Dial-in tab of the users properties window via Computer Management/System Tools/Local Users and Groups/Users/user, for example "Always Callback to: 999999".
I am also able to do this programmatically via the mprapi library call MprAdminUserSetInfo(), regardless of whether Routing and Remote Access has been set up or not.<br/>
<br/>
On Windows Server 2008 EE SP2 I am able to set Callback Options for a user on the Dial-in tab of the users properties window via Server Manager/Configuration/Local Users and Groups/Users/user, for example "Always Callback to: 999999". However, I
am *unable* to do this programmatically via the mprapi library call MprAdminUserSetInfo(), regardless of whether Routing and Remote Access has been set up or not.<br/>
<br/>
On 2008 the MprAdminUserSetInfo call returns the error code 1003, or "Cannot complete this function".<br/>
<br/>
Given that the same code works on WS 2003, and that the native Server Manager UI is able to set the callback number, I cannot understand why mprapi is returning a 1003 error code.<br/>
<br/>
Any help would be much appreicated!<br/>
<br/>
<br/>
To run the code sample, just type: admapit.exe \serverName userName<br/>
<br/>
Both my 2003 and 2008 servers were members of workgroups, not domains.<br/>
<br/>
<br/>
On Windows 2003 I get:<br/>
<br/>
