Top 3 Reasons for the "The server instance specified was not found. Please specify the server's address and port." Error

The easiest way to install web parts is probably to use this utility from Microsoft called Install Assemblies - very simple and intuitive interface, takes care of creating the Safe Control entries and even creating DWPs for your web part assemblies.

Install Assemblies internally uses STSADM.EXE - more than often you will face the infamous "The server instance specified was not found. Please specify the server's address and port." error. There can be many reasons why you will face this problem, here are top three reasons I've seen in the field either while installing web parts or while using Object Model code -

1) WSS SP1 not installed on all components

Diagnosis: Go to SharePoint Central Administration -> Click Windows SharePoint Services -> Click Extend or Upgrade a Virtual Server (Second Link) -> In the virtual servers listed, do you see "Upgrade" next to your SharePoint virtual server.

Resolution: Upgrade all your components to SP1 using the STSADM.EXE util -> follow steps listed in this KB article

https://support.microsoft.com/?kbid=871149

2) You receive the above error when using SharePoint Object Model code and using the Hostname/Fully Qualified Domain Name (FQDN).

Resolution: Follow this support article https://support.microsoft.com/?kbid=832816

3) You are using SSL, your code works fine while using https://sitename but not https://sitename

Resolution: Use the IP address with https:// instead of the sitename (eg SPSite testSite = new SPSite("https://65.12.12.12");

    For us, it was reason #1 whereas all the googling in the world will point you to reason #2. Thank you for the post, you saved me and my deployment team a great deal of pain&suffering at the hands of our management. My question is, though: How did you make the connection between #1 and the problem? I see nothing that would link the two.

    add #4:
    "If the Default Web Site in IIS is set to a port other than port 80, the Typical Installation for Windows SharePoint Services may end without creating a site."

    Hi,

    We have service that use .Net WebClient class to call https://spsites.testserver.com/sites/yukonbp/_vti_bin/owssvr.dll?Cmd=GetUsageBlob&BlobType=Current to get blob data for site Yokonbp. When SSL is enabled (required) I'm getting "The server instance specified was not found.  Please specify the server's address and port." If SSL is not enabled it works fine without any issue


    The SSL matches the FQDN.
    Do you happen to know why it is giving this error or can you please point to someone who can help find a solution for this?

    I would appreciate the help

    Just to share i just faced this issue and I found that these three were not the only issue. I faced this issue twice and none of the time, the issue os was any of three.

  1. First time, appPool was configured corrcetly. It was set diff in ISS and diff in central admin site.
  2. Second time, default site in ISS was deleted.

    I have a Windows Server 2003 SP2 with Sharepoint Portal Server SP2 and WSS 2.0 SP3.  In 2006, I had installed several custom web parts to the GAC using the Stsadm tool. The virtual server may need to be upgraded, based on the version number I am seeing in Central Administration. Now, I tried to install another custom web part using the same tool, but I get the error message "The server instance specified was not found. Please specify the server's address and port." The Virtual Server is configured with an IP address of "(All Unassigned)". I tried specifying an -url parameter to Stsadm with the server name, server IP address and port 80, but nothing works. I can enumerate the existing web parts with the Stsadm tool. I don't know where to proceed from here. Can you please help?

    I found this was caused by another issue. I've blogged about it here: spfarm.blogspot.com/.../stsadm-server-instance-specified-was.html Thanks Howard
