Error:

Cannot navigate to the requested page while User Profile Synchronization is running. Please wait for the current Synchronization run to finish.

Reason:

You will get this error, in case if you are trying to "Import the User profiles" in SharePoint 2010. Sometimes, "The user profile sync" job may not be running or it may be in "Starting" stage for a long time. 

You can check this status in central admin as I said below. 

• In central admin, go to "Monitoring" link 
• Then go to "Review Job definitions"  under "Timer Jobs"
• Then click the "Running Jobs" link in left hand side.

Here you can see that the sync job will be running continuously. Reason is the required services may not be ready after the SharePoint 2010 installation.

So, what to do?

Solution:

Solution is very simple. Just login into the SharePoint server and go to the command prompt with administrator privileges (right click on the "Command Prompt" icon and select the 'Run as Administrator' option).

Then,  just type "IISReset" to reset the IIS.

Now you can come and check the Running Jobs link as I mentioned above. 

Thats it...
