Sami,please check first whether all features (on site/site collection/farm level) that were used on your source site are deployed on your target site, too. The following part of your stacktrace indicates that an assembly could not be loaded: Exception Details: System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E) Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace:[FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E)] System.Reflection.Assembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) +0You can also check trying to open your default.aspx by SPD and figuring out which error is thrown there.

Dear Markus,Thanks for your reply.All the features on the target and source machine are the same but I tried to open the site in SharePoint Designer it gives me an error stating:"The folder http://mysiteurl isn't accessible. The folder may be located in a unavaliable location, protected with password or the filename contains / or \"Please suggest me some other solution if you have any?Thanks,Sami

Go into Central Administration and make sure that "User Permissions for Web Application" and the permission option titled "Use Remote Interfaces - Use SOAP, Web DAV, or SharePoint Designer interfaces to access the Web site" is checked. Same goes with Central Administration -> Application Management ->Authentication Providers where "Enable Client Integration" should be checked.Now try again opening your site (WITHOUT default.aspx in the URL).Are you also sure that the same features are ACTIVATED on both your source as well as on the target web application/site level?

Dear Markus,Both the options which you have stated in your reply are checked. Just to let you know that I have to transfered the web app from on server Farm to another in Such a manner that I have taken backup of the content database from from development server and have attached the database on the new production server beacuse the backup and restore option was not restoring the content database.Then I created a new web application and used that content database for it. Since the site was using publishing feature on the dev server therefore I have created the new web app and site collection using the Publishing->Colloboration portal template on the new server.Then I run the restore process and the site was restored and I didn't have to care about the content database because I have already transferrd it through SQL Server.Other than that I have also copied the dlls from the bin folder of the dev server to bin folder of the newly created web app.Please let me know of further suggestions? Thats a life saver task for me?Thanks and Regards,Sami

your target web app, does it use client integration or form based authentication? If the last one, switch it temporarly to integrated authentication.Now try again opening your site (WITHOUT default.aspx in the URL), in this formhttp://server/siteWhat does your SPD shows to you?

I have noted that in source web application I have three authentication providers i.e . for the default zone I have a membershipprovider name which is based on form based authentication while for the Intranet and Extranet zone the membership provider name is just windows. While in the destination I just have one default zone and the membership provider name is windows. I tried to change the authentication provider name to forms based while giving it the same name as given in the source app but still no luck. Should I extend my new web app to include the two zone with the provider name of windows against it? and Why it is not picking these extended web app and zones while I have restored the site from central administration backup and restore capability. Any suggestions?Besides that the spd gives the same previous error.Thanks,Sami

Sami Khan,seems like that error which you provided in original post was taken from event log. Unfortunately it doesn't show name of missing assembly. In order to determine what exact assembly is missing you can do the following:1. First of all see sharepoint logs located in 12/logs folder. These logs can contain name of missing assembly. Most probably here you will have several log files. See log file which corresponds to datetime of occured error, open it and try to search string "Assembly._nLoad". If you will find occurences of this string then most probably you will find assembly name in near lines2. If 1st approach will not give results - try to use Assembly Binding Log Viewer (Fuslogvw.exe) - http://msdn.microsoft.com/en-us/library/e74a18c4(VS.71).aspx. It will show you all errors occured during .net assemblies bindingshttp://sadomovalex.blogspot.com

Thank for your reply. After running the Fuslogvw.exe..The following log entry was returned:The operation failed.Bind result: hr = 0x80070002.

I have found out that there were lot of system dlls missing on my machine.. I have reinstalled the widows OS and my SharePoint Sites are up and running again.
