Please check that dotTrace and your IIS application has the same rights level: as far as I remember, IIS is always started "as administrator", so try to launch dotTrace "as administrator" as well.
Please let me know if it doesn't help.
I am launching application as administator...
Do you mean the application you're profiling or dotTrace?
...I have logged in as administrator on the box...
This is not enough unfortunately. Please right-click on dotTrace's .exe file (or on dotTrace in Start Menu) and select "Run as administrator".
I mean the dot-trace application. The IIS is runing localsystem, and uses IUSER_<machinename> as impersonation.
In Windows Server 2003 there is no such thing as "Run as Adminsitrator". The UAC was not invented then.
I can right-click and select "run as..." then I can enter administrator account information, but that gives the same result.
Thanks for your patience! So if the problem is not the rights level, could you please give me more details:
1. what exact version of dotTrace do you have? It's available in Help -> About.
2. please open Windows Event Viewer and check that there're no errors like "failed to load profiler". If there are any, please send me the details.
3. in process explorer for each running (when your app is working) w3wp process view which user owns it and send me the names of this users.
4. get dotTrace's core logs; here's the guide, but please enable also MetaDataGt checkbox after step 6.
Maybe it would be more convinient to you if we try to organize a kind of remote debug session? We'll connect to your machine and look at dotTrace's behaviour; all the operations we perform will be under your full control.
BTW, do you already have dotTrace license? Because if you don't we'd like to give you one for you help in investigating this issue.
Unfortunately I have no access to your email in profile So please contact me: email@example.com.
For remote debug we usually need Process explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653) and Process monitor (http://technet.microsoft.com/en-us/sysinternals/bb896645) - Windows tools for easier working with processes; Far manager (http://www.farmanager.com/index.php?l=enhttp://www.farmanager.com/index.php?l=en) - a file manager that helps to browse different types of files with ease; and TeamViewer (http://www.teamviewer.com/ru/index.aspx) for connection. Please install them.
As for time, our developer is in same time zone as you, so what about 19:00 today or tomorrow?
