Could not load file or assembly ‘PresentationCore’ or one of its dependencies. An attempt was made to load a program with an incorrect format.

although everything was working fine when running the site on my machine (32bit WinXP with IIS 6).

I did some research, and some people suggested to turn on “Enable 32-bit Applications” in my web site application pool advanced property. However, I was not satisfied with that answer. All my DLL’s were supposed to be compatible with 64-bit, so I did not see why I should turn on that setting.

One thing I have to mention here is that I was using MSBUILD to compile my web application on the server with a line like:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Msbuild.exe Extranet.csproj /t:Build

After much researching, I noticed that each time the project was compiled with the line above, two files were added to the bin directory of my web application:

• PresentationCore.dll
• System.Printing.dll

I never added these files to the project, and I did not reference them either. They were added automatically by MSBuild every time I would compile. This was the culprit. After doing more investigation, I discovered that if I compiled with the proper version of MsBuild, this did not happen anymore. So I changed my compiling line above for this one and everything was fine or almost:

c:\Windows\Microsoft.NET\Framework64\v3.5\MSBuild.exe Extranet.csproj /t:Build

Notice the changes: Framework -> Framework64 and v2.0.50727 -> v3.5.

Earlier, I said that using that version of MsBuild solves everything or almost because I then got some compilation errors, but they are easy to fix. I did not have Visual Studio installed on the server, so two sets of files were missing for the compilation to succede. The compiler was complaining about WebAppications.targets and WebProfileBuilder.targets. If this happens, you can simply copy the follwoing folders from a machine where you have Visual Studio installed to your server:

• C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\WebAppications
• C:\Program Files\MSBuild\WebProfileBuilder

After doing so, everything complied fine, and I did not have any complaint about PresentationCore anymore.

Hope this helps!

EXECUTE msdb.dbo.sp_send_dbmail @recipients='address@domainname.com',
@subject = 'Test email',
@body = 'Test email body'

The solution was to add the user I was using to run the above query to the msdb database and to assign the role DatabaseMailUserRole to the user:

EXEC msdb.dbo.sp_addrolemember @rolename = 'DatabaseMailUserRole'
    ,@membername = 'myUserName';

• Open the following folder: /Library/Preferences/SystemConfiguration
• Delete these files: com.apple.airport.preferences.plist, NetworkInterfaces.plist and preferences.plist
• Reboot your Mac

I found this solution here, and it worked for me. Here is another similar solution in case the one I used does not work.

http://superuser.com/questions/89266/whats-causing-all-the-disk-activity-on-os-x

There are two suggestions on that thread. Either using ‘iotop -C 5 12' or using 'fs_usage'.

What I would like to find though is a tool that would analyze my Mac’s resources over a full day of work and that would report what should be tweaked. I don’t know if such a tool exists though. I you know of one, please let me know.

One thing I have to tell though is that PPA Int’l support is very poor. I got only one reply from them telling me to try the drivers from the JMicron web site, which did not work with OS X 10.5.x. After I have never been able to get anymore support from them. They would not reply to my e-mails.

I haven’t tried though to boot from an external drive using the eSata card.

exec sp_change_users_login 'report'

In order to fix this, the logins for the reported users will have to be created on the new server if they do not exist.

If the logins are the same as on the original server, it is easy to fix the orphaned users. Simply issue the following command for each orphaned user:

exec sp_change_users_login 'auto_fix', '<replace this by the username...>'
