When users begin to complain about accessing SharePoint it’s always a good idea to know where to start looking.  One of the first things to check is whether the SharePoint site is locked or in a read-only status.

In Central Administration, check the status of the site collection. This can be found under Application Management > Site Collections > Configure quotas and locks

The site collection is showing as “Not locked”.

In Central Admin, check to see if the database itself is locked. Under Application Management > Manage content databases

INext check the database to see if it is set to single user, read-only, or if the database is not in ‘NORMAL’ state.

This is the STSADM equivalent of setting the site collection lock status under Application Management > Site Collections > Configure quotas and locks. So now by rolling the SharePoint site-lock,

all being well the site will be back to an accessible state.
