No comments

In this article we will learn about when we get “Server error: http://go.microsoft.com/fwlink?LinkID=177673” from SharePoint sites and how to fix it.

Issue Description

During our SharePoint content database migration we have faced this issue.
Lets say we have migrated the content database from SharePoint one version to another version(for example SharePoint 2010 to SharePoint 2013). We have migrated the content database successfully without any error but when we try to access the SharePoint site from the browser, none of the sites gets opened in the browser and we’ll get the below error.
Server error: http://go.microsoft.com/fwlink?LinkID=177673

SharePointServerError

No need to panic for this, here is reason for this error and fix.

What is the reason for this error?

If we go to the “/_admin/FarmServer.aspx” page from the central administration and if we have multi severs farm – we can see one server status shows as “Upgrade Blocked” while another one shows as “Installation Required” as below:

I will explain what are these two status means.

UpgradeBlocked

Upgrade Blocked

The server is blocked from the upgrade. The current server is installed with latest CU and it will remain blocked until all the SP servers in the farm are installed with the same version.

Installation Required

The server still not yet installed with the same CU that is already installed on other servers.

If we summarize the above we will get the below:
The latest windows updates were installed in the first server where the status shows as “Upgrade Blocked” but in another server the same windows updates were not installed , so the status was showing as “Installation Required“.

How to fix the above error?

Now install the windows updates in all other servers in the farm where the status shows as “Installation Required“. Now browse all the SharePoint sites where you were getting the above highlighted error – everything will be opened fine.

Summary

Thus, we have learned in this article reason of “Server error: http://go.microsoft.com/fwlink?LinkID=177673” and its fixes.
