Cannot connect to SQL until after service is restarted

A new database and application was installed on my SQL Server. Recently
users cannot connect to the database. I cannot even connect with Enterprise
Manager or Query Analyzer. Some users were getting an error message telling
them there was not enough memory.
I am getting the following message in the logs:
WARNING: Failed to commit contiguous memory of Size 65536.
I've configured the SQL Server system to allocated up a minimum of 512MB and
a maxium of 2GB of memory.
Are there any thoughts on how to resolve this problem? Thanks for your
attention.
Tech Details:
SQL Server 2000 Standard
OS: Windows Server 2003 (Small Business Server 2003)
2 Processors (P4 Xeon 3.06Ghz)
4GB memory
Application (Zoll Data Systems?)Can you post the output from sp_configure? Preferably also attach as a text document to preserve
formatting.
