I recently got this error when trying to run the SharePoint Subscription Edition Search.

The solution for me was items 1 and 2 in this blog post https://social.technet.microsoft.com/wiki/contents/articles/25863.access-is-denied-verify-that-either-the-default-content-access-account-has-access-to-this-repository-or-add-a-crawl-rule-to-crawl-this-repository.aspx

This is the post, just in case it ever disappears.

Introduction

Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository.

Issue

Once we configure Search and started all the Related services, when we start the Crawl and crawl failed and shows one of the errors below. This contains all the issues and solutions related to “search crawling” in one plate that everyone can easily able to get the solution quick. All the issues and resolutions are below.

Errors

1. Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository. If the repository being crawled is a SharePoint repository, verify that the account you are using has “Full Read” permissions on the SharePoint Web Application being crawled. (HttpStatusCode Unauthorized The request failed with HTTP Status 401: Unauthorized.)
2. “An unrecognized HTTP response was received when attempting to crawl this item. Verify whether the item can be accessed using your browser.”
3. “The secure sockets layer (SSL) certificate sent by the server was invalid and this item will not be crawled.”
4. The URL of the item could not be resolved. The repository might be unavailable, or the crawler proxy settings are not configured.

There could be many reasons that search is not working properly even when we configured everything good. This article is providing all the relevant and related solutions to check. Every solution that you need to take into consideration and apply to resolve the issues. One of the mentioned solutions that definitely work and resolve the issue.

Solution 1

Disable Loopback Check: It is actually a security feature that prevents access to a web application with a fully qualified domain name to from the host server. Follow these steps to disable this feature

· Click Start, click Run, type regedit, and then click OK.
· In Registry Editor, locate and then click the following registry key:
· HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
· Right-click Lsa, point to New, and then click DWORD(32-bit) Value.
· Type DisableLoopbackCheck, and then press ENTER.
· Right-click DisableLoopbackCheck, and then click Modify.
· In the Value data box, type 1, and then click OK.
· Quit Registry Editor, and then restart your computer.

Solution 2

Specify host names: To specify the host names that are mapped to the loopback address and can connect to Web sites. This method would be preferred for NTLM authentications.

· Click Start, click Run, type regedit, and then click OK.
· In Registry Editor, locate and then click the following registry key:
· HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
· Right-click MSV1_0, point to New, and then click Multi-String Value.
· Type BackConnectionHostNames, and then press ENTER.
· Right-click BackConnectionHostNames, and then click Modify.
· In the Value data box, type the host name or the host names for the sites that are on the local computer, and then click OK.
· Quit Registry Editor, and then restart the IISAdmin Service

Solution 3

Check the Permissions correctly: This item should need to check in many areas. Be patient and check one-by-one to ensure that all set correctly

Check 1

When you’re crawling the search. Make sure that the default content access account (crawl account) has access to the User Profile Service
· Open the Central Administration and go to Application Management
· Click Manage service application in the Service Application section
· Select the User Profile Service Application and click on Administrators
· Add your content access account and give it the Retrieve People Data for Search Crawlers permission

Check 2

When you’re crawling the search. Make sure that the default content access account (crawl account) has access to the Search service.

· Open the Central Administration and go to Application Management
· Click Manage service application in the Service Application section
· Select the Search Service Application and click on Administrators
· Add your content access account and give it the Full control permission

Check 3

When you’re crawling the search. Make sure that the default content access account (crawl account) has access to the web applications that are crawling.
· Open the Central Administration and go to Application Management
· Click on web applications
· Select the web application -> check the user policy on Ribbon
· Add your content access account and give it the Full control permission

Solution 4

Host Headers: If you’re using a multi-server farm, having the below servers in farm.
· Server A - Application server
· Server B – WFE
· Server C- Crawl server

We need to create the Host headers in All the WFE, Crawl servers to crawl the Content. Go to below path and create the headers. Refer below article:
http://expertsharepoint.blogspot.de/2013/10/path-for-host-file.html

In the Headers,
· For WFE servers- Need to put the Server IP of the local server
· For Crawl Server- Need to put the Server IP of the WFE server

If you have multiple WFE,Crawl servers. You need to choose one of WFE server IP and put the same IP in all WFE, crawl servers also.
Note: We can apply these solutions one after one and test the status of crawl.

Note: Resolved the issue by above method. If you find a different solution, please report it as a comment to this post. This will be useful to SharePoint community. Be sure to double-verify it: undo your solution and verify that the problem comes back, then redo it and verify that the problem goes away.

Public Function IsACCDE() As Boolean
    ' This property exists only in compiled DBs (.mde, .accde)!
    On Error Resume Next
    IsACCDE = (CurrentDb.Properties("MDE") = "T")
End Function

This code returns True if MS Access has been saved as ACCDE and False it it has not. This is different than the built in IsCompilled() function that return True or False based on the actual code being compiled or not.

From here: windows - 'The Online Service is not available' Issue in Visual Studio Professional 2013 with Update 5 - Stack Overflow

I have worked in vscode 2013 until today. But when I'm trying to open my IDE in today morning, it gets 'Your license has gone stale and must be update' error message as following.

and after I tried to update license and sign In operations. when I'm trying to these two it gets 'The Online service is not available. Please try again later' error message as following.

I'm using windows operating system. Is anyone know how to solve this?

Solution:

ry this; it worked for me. Just add two DWORD values to the Windows Registry. Site go.microsoft.com now supports only TLS1.2 protocol.

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319]

• "SystemDefaultTlsVersions"=dword:00000001
• "SchUseStrongCrypto"=dword:00000001

Cannot get Outlook e-mail from O365. Error is Need Password.

Solution: Update Registry Key: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity\DisableWinHttpCertAuth to 1

If this is ok, setting the below registry key to 1 in below path often resolves it:
Path: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
Key: DisableADALatopWAMOverride (DWORD)

For some reason I could not update my VS 2013 license today! The service was not available until I entered these registry Keys!

I received the following error when I was attempting to compare columns in a SQL query between two tables located in two separate databases. In this case, the collation settings between the two databases were configured differently. Rather make any changes to the databases, I was able to apply a simple fix to my SQL query: In fact even when I changed the Collation in the Database it still did not Join!

ORIGINAL QUERY –

SELECT        TOP (100) PERCENT dbo.MyLoans.LoanNumber AS [Loan Number], LoansDW.dbo.TAP.BorrFirstName AS [PB First], LoansDW.dbo.TAP.BorrLastName AS [PB Last]

FROM            EncompassDW.dbo.TAP RIGHT OUTER JOIN

                         dbo.FiveStarLoans ON LoansDW.dbo.TAP.LoanNumber = dbo.FiveStarLoans.LoanNumber 

ORDER BY [Loan Number]

FIX –

Simply apply the default collation to the fields you are comparing.

SELECT        TOP (100) PERCENT dbo.MyLoans.LoanNumber AS [Loan Number], LoansDW.dbo.TAP.BorrFirstName AS [PB First], LoansDW.dbo.TAP.BorrLastName AS [PB Last]

FROM            EncompassDW.dbo.TAP RIGHT OUTER JOIN

                         dbo.FiveStarLoans ON LoansDW.dbo.TAP.LoanNumber = dbo.FiveStarLoans.LoanNumber COLLATE DATABASE_DEFAULT

ORDER BY [Loan Number]
