How to resolve "Access to the port is denied" error?

Question

When trying to set up a new Team Project (or when running the Best Practices Analyzer) for TFS 2008, I keep getting this error:

 

Event Type: Error
Event Source: ASP.NET 2.0.50727.0
Event Category: None
Event ID: 1334

Application ID: /LM/W3SVC/1843996332/Root

Process ID: 2780

Exception: System.UnauthorizedAccessException

Message: Access to the port is denied.

   at System.Threading.ThreadHelper.ThreadStart()

 

Any ideas how to fix this?  (Is there some permissions that need to be granted to a specific user account?  If so, which one?)

Answer 2

Hello Dave,

 

   Could you please check if the user has the admin permission on the Sharepoint Server?

 

   If you are using WSS 3.0

 

   Try to add a user or group to the Farm Administrators group and the Site Collection Administrators group in Windows SharePoint Services 3.0

 

     More in How to: Set Team Foundation Server Administrator Permissions

 

   And could you please check the port assignment of Sharepoint and Sharepoint Administrative Site.

 

   More in  How to: Verify or Correct Port Assignments

               How to: Verify or Correct IP Address and Domain Name Restrictions

         

 

   Also please check if there is any firewall blocking the port used by the Sharepoint Site and the Sharepoint Administrative Site.

 

    Good luck.

 

 

Answer 3

 

Looking through the "How to: Set Team Foundation Server Administrator Permissions" document, I verified that the my user account was in the Team Foundation Administrator's security group and in the Farm Administrator's group and the Site Collections Administrator's group.

 

It's when I try navigating to the URL:

 

http://teamsys/Reports/Pages/Folder.aspx

 

I get the following warning in the event log, followed by the same error as described above:

It looks like some kind of configuration problem with Report Server on MOSS.  Any ideas on how I might fix this?

Answer 4

I found this entry:

 

http://rfinn.spaces.live.com/blog/cns!4E19D0E183DFC38B!180.entry

 

that describes the same problem.  So I copied the <sessionState> element:

 

<sessionState mode="SQLServer" timeout="60" allowCustomSqlDatabase="true" partitionResolverType="Microsoft.Office.Server.Administration.SqlSessionStateResolver, Microsoft.Office.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

 

from the web.config of the MOSS site to the Reports sub-site.  (The ReportsServer sub-site has session state disabled, so I didn't modify it.)

 

I then restarted IIS and tried the Reports url again.  This time I didn't get the configuration error, but I did get the "Access to the port is denied" error.

 

Any ideas?

 

Thanks,

-Dave

 

Answer 5

Is the problem possibly due to the fact that Report Server and MOSS are on the same Port 80?

Answer 6

Ok, I think I've resolved this issue.  My understanding was that the TFS installation would take care of the configuration of SQL Reporting Services.  Well, it appears that it doesn't quite set everything up correctly.

 

I ran Reporting Services Configuration, and did the following:

1. Used IIS Manager to change the service account of the Report Server application pool from NETWORK SERVICE to the same service account as I was using for MOSS and TFS.
2. Started Report Services Configuration, selected the Web Service Identity tab and verified that the Report Server application pool was used for both the Report Server and Report Manager applications.  Then I selected 'Apply' (this, I believe, assigns the proper permissions to the service account).
3. Restarted IIS.

At this point, I could then browse to http://teamsys/Reports/Pages/Folder.aspx.

 

Maybe I missed the instructions in the installation guide for configuring Reporting Services AFTER installing TFS.

Hi Guys,

 

Had the exact same thing happen to me today. I had used a seperate domain account for my SSP creation, and had no trouble with the creation itself. Problem happened when I clicked on the SSP link. Decided to put the account (used to create SSP) under the Owner group permission in Central Administration. Having no problems now, am pleased to note.

 

Do you guys think this approach is safe? Is there an alternate, more secure approach? Any advice would be appreciated.

 

Thanks,

This has worked for me after recently upgrading from SharePoint 2003 to SharePoint 2007.  Even though the ApplicationsAppPool app pool worked well with the Network Service account before the SharePoint upgrade, after the upgrade I had to switch it to use the same domain account used by MOSS. Now I no longer get the "Access to port is denied" error. Thanks!
