Can't reinitialize a subscription

We have a Snapshot Replciation that suddenly stopped working.  I can generate a new snapshot, but when I try to reinitialize the subscriptions, I get the following:

TITLE: Replication Monitor
------------------------------

Replication Monitor could not reinitialize one or more subscriptions that support automatic initialization.

For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.0.1600.22&EvtSrc=Microsoft.SqlServer.Management.UI.ReplicationDialogErrorSR&EvtID=CantReinitAllSubs&LinkId=20476

------------------------------
ADDITIONAL INFORMATION:

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

------------------------------

The subscription status of the object could not be changed.
Could not update the distribution database subscription table. The subscription status could not be changed.
Changed database context to 'ReportUtility'. (Microsoft SQL Server, Error: 14068)

For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.00.2531&EvtSrc=MSSQLServer&EvtID=14068&LinkId=20476

Also, when I right click on the subscription in SSMS, and choose properties, under the "Status of Last Synchronization", it shows "The process could not connect to the Distributor [name]".

Any ideas?  Thanks!
