Error inserting record in IDENTITY column

Hi,
I have a counter field with data type IDENTITY in a table which should have
primary key constraint to that ID field.
When it tried to insert a new record, it has error "cannot insert duplicate
key in the counter field" because of the constraint.
Supposed that whenever adding a new record, it should add the increment to
the last ID. How can I fix it to allow inserting new records ?
Regards,
JTWhat version of SQL Server? Seems like the internal counter for the identity value is messed up,
something I haven't seen since the 6.5 days. Read up on DBCC CHECKIDENT, that should be able to fix
it for you.
Of course, I assume you don't use SET IDENTITY_INSERT ON and specify a value for the identity
column.

How do you insert the values?
create table #tmp (id int not null identity(1,1) primary key, c char(1) not
null)
go
insert into #tmp(c) values ('a')
insert into #tmp(c) values ('b')
insert into #tmp(c) values (c')
go
select * from #tmp
