How to migrate IIS6 web.config to IIS7

George — Fri, 21 May 2010 20:15:38 +0000

If you are using custom httpHandlers or httpModules, you would need to
run the migration command below.


C:\> %systemroot%\system32\inetsrv\APPCMD.EXE migrate config "domain_name.com/virtual_directory"
Successfully migrated section "system.web/httpModules".
Successfully migrated section "system.web/httpHandlers".

Now if you are going to migate the web.config inside the WEB_ROOT directory itself and not inside any virtual directory don’t miss a forward slash, / after the domain name.

eg:


C:\> %systemroot%\system32\inetsrv\APPCMD.EXE migrate config "domain_name.com/"
Successfully migrated section "system.web/httpModules".
Successfully migrated section "system.web/httpHandlers".

Otherwise you may get an error like below,

ERROR ( message:Cannot find APP object with identifier “domainame.com”. )

Solving “Service Unavailable” message just for one website in Plesk and IIS7

George — Mon, 17 May 2010 17:16:24 +0000

A particular website of a client was getting “Service Unavailable” message for just one website in a Plesk server while all other website was working fine. No logs in Event Viewer were giving any clue. However when someone changed the Application pool to use the shared pool plesk(domain2.0)pool, it was working fine which deserted the issue to application pool issue.

Approach to the solution

Check the application pool running, by taking Start => Run => inetmgr
Find out which application pool a website is running by taking the IIS Manager => Sites => domain.com (domain in question) and right column of options => Advanced Settings => General => Application pool
Expand application pools and check whether the application pool is stopped and if it is in the stopped status, start it.
As a good measure, please recycle the application pool as well.
If it fails to start, check whether the application pool generates any event logs. Next measure is to reset the password of IUSR_username
For resetting the password of IUSR_username, go with the below steps,
1. Login to the server by RDP
2. Retrieve password of the domain owner from Parallels Panel database running this command:
  
  “%plesk_bin%”\dbclient –direct-sql –sql=”select su.login, a.password from accounts a, sys_users su where a.id=su.account_id and su.login=’username’ ”
  
  login password
  username password
  
  where username is an owner of the domain, which can be taken from Plesk => Domains => Web Hosting Settings
3. Synchronize system password with accordance of retrieved one as follow:
  
  net user IUSR_username password
Try restarting the application pool again and if is works well, all is good, or else, check to see further options, like Handler Mappings or ISAPI_Filters. But Handler Mappings or ISAPI filters usually affects only one or two types of file extensions.

MSSQL – Two common issues while restoring a backup and it’s solutions

George — Sat, 27 Feb 2010 02:35:54 +0000

There are two most common issues while restoring the database (usually ending in .bak format).

First error
System.Data.SqlClient.SqlError: The backup set holds a backup of a database other than the existing ‘user_database‘ database. (Microsoft.SqlServer.Express.Smo)

Solution for First error

Connect to the database server

Go to the restore option and select Restore Database

On the Restore page that loads up, make sure that the Destination for restore has the database you want to restore and in the Source for Restore, choose From device: And browse by clicking [..] and Add the file location there, the location where your database backup resides. You may need to browse the backup. If you get permission denied, copy the bak in the MSSQL folder.

Attaching the database backup file

Restore it. Make sure that the Restore Checkbox is selected. And Click OK. And get ready for the error

Here comes the first errorSystem.Data.SqlClient.SqlError: The backup set holds a backup of a database other than the existing ‘user_database’ database. (Microsoft.SqlServer.Express.Smo)
And the solution is to go to Options -> Overwrite Existing Database . But if you aren’t so lucky, you will be welcomed by another error as seen below. where it’s solution is to edit the path from D:\ to C:\ or whichever Drive, where your MSSQL is installed.

System.Data.SqlClient.SqlError: Directory lookup for the file “D:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\user_database.mdf” failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.Express.Smo)

Both THE Solutions are in a single screen shot. The final screenshot

Just edit D:\ProgramFiles\Microsoft… to C:\ProgramFiles\Microsoft or whichever directory where you installed the MSSQL server. Don’t keep database server on your system drive C: though.

HTTP 405: The HTTP verb used to access this page is not allowed

arnold — Thu, 25 Feb 2010 20:53:12 +0000

On an html page, one of our customers was getting this issue. Despite asking him to change the extension to .asp, he insisted to have html extension and still process the HTTP verbs, where it is POST method here.

Situation becomes like this a static page wants to be read a dynamic page and process the values obtaining from POST method. Solution is to make the .html read as .asp with asp dll, just like we do html parse as php in Linux boxes Here are the steps to do it on a Windows 2003 machine

1. Start –> Run –> inetmgr
2. Websites –> website/domain name in question
3. Right Click on the domain –> Properties –> Home Directory –> Configuration
4. In the tab Mappings –> Add an extension for .html and .htm , if it is missing (most cases it will be missing) and edit to add all verbs (POST, GET, HEAD are needed)
5. Fields to be added are as below,

Executable : C:\WINDOWS\system32\inetsrv\asp.dll
Extension : .html
Limit to : GET,HEAD,POST,TRACE

And Click Apply, OK All is well !!

Bad Request (Invalid Hostname) when accessing via IP

George — Tue, 29 Dec 2009 19:19:57 +0000

Customer wanted to have a dedicated IP, but once I change the IP from the plesk control panel, I couldn’t get the website when accessed using IP. Instead, it was giving me the plesk control panel’s default page. Reason ? Default Website was having the IP as “All Unassigned”. Set that to the main IP address. But after that I was getting a new error.

What I could get was “Bad Request (Invalid Hostname)” in bold letters. Here is what I did to fix the same.

Start -> Run -> inetmgr -> Expand the (+) -> Websites -> Right click on the domain name -> Take Properties -> Website -> IP Address (make sure that it has the dedicated IP assigned there) and then click “Advanced”

Add/Edit Web Site Identification

IP Address : Choose the dedicated IP from drop down list
TCP/IP Port : 80
Host Header Value : Leave it blank (Important)

Leaving the Host Header Value should fix the issue and fetch the website when accessing it using the IP.

One website in Plesk is asking for user name and password. What is the solution

George — Fri, 17 Apr 2009 08:18:55 +0000

This is common issue, but solutions varies based on situations. It could be one or a combination of a solutions listed below. If you had to go through another solution to solve it, please add it over here for others.

Permission issue was making the website to ask for the password. Run the Plesk permissions fix from the Plesk reconfigurator. It could help you 10% of the time
If it is asking for username and password, right after you changed the password of the account, 80% of the cases, below command based solution would work.

cd %plesk_bin%
websrvmng –update-anon-password –domain-name=domainname.com
Login to plesk, select the domain, click web directories. And there, select the the protection tab and click remove protection if enabled – Only 5% chances to have this solve your issue
Try resetting the domain password from Plesk, with Additional Write/Modify permissions checked. This may sync the IUSR_username’s password and the Plesk/FTP password. If it didn’t move on to next option to manually synchronize it.
Go to IIS > Web sites > domainname.com > Properties > Directory Security tab > Click on Edit button within “Authentication and access control” section > enter “password” in password filed > click OK.
After that, Go to Users Management > find user IUSR_pleskusername > Right Click > set password > proceed > enter “password” > click OK. If this also didn’t fix, issue is much more serious and move on to next options
Depending on the Plesk versions you use, Plesk group `psacln` should be allowed to access the server from the network. For that Go to, Administrative Tools > Security Settings > Local Polices > User Rights Assignment > Access this computer from the network
Check whether there is any new FTP accounts added with the “Home directory” as httpdocs itself. If so please remove it and then change the password at Domain Setup and save it
Check whether the plesk_username and IIS_pleskusername are added and has proper permissions for the DriveLetter:\Inetpub\vhosts\domainname.com as well as DriveLetter:\Inetpub\vhosts\domainname.com\httpdocs.

Okay those are my current solutions.
