[dba-SQLServer]SQL Server 7 and SP 4

Hello All,

Firstly, I have had a good look at the knowledge base and also in Deja to
check to see if my question has already been answered.  There are a few
similiar issues reported but I do not think that there is a matching one.

I have SQL 7.0 SP 2 installed  on Windows 2000 SP 2.

Two days ago, I tried to install SQL 7.0 SP4 on the machine.  Everything
went smoothly except for an error message suggesting that 'something' is
trying to overwrite the certain system files and that they are from an
unknown source.  The message box does offer the choice to ignore, which I
presumed at the time allows the installtion to proceed.

The remainder of the installation went without any other issues.  When I
finished the installation, the version is still the same, it appears that
the SP2 has not been applied.  I am confused because it appeared to have
worked.

Does anyone have any suggestions or similiar experience ?  There seem to be
a number of similiar issues with failed installations of SP's.

Your help and time is appriciated,

Thanks in advance,

Mark Breen
