Your tempdb database is now on the device you created.

Use sp_configure to remove tempdb from RAM.

Cancel the selection of the master device as the default device.

Create a new device to hold your tempdb database, and select it as the default device.

Use sp_configure to put tempdb into RAM.

However, here's our recipe for shrinking tempdb: Tempdb defaults to 2MB, so you generally want to expand tempdb rather than shrink it. We see tempdb-related questions often in SQL Server newsgroups. What is the best way to make my tempdb smaller? However, to contain potential security problems and not degrade performance, your best option is to put SQL Server on a member server rather than a domain controller.

You can avoid these security holes (even if you install SQL Server on a domain controller) by running MSSQLServer under an account other than LocalSystem and without domain administrator privileges. This command lets sas turn their personal NT accounts (i.e., with ordinary user privileges) into a domain administrator account. For even more fun, a SQL Server system administrator (sa) can type

This command is a full recursive deletion of the root directory. Thus, users who have the right to execute xp_cmdshell also have the right to perform This result is benign, but xp_cmdshell executes in the same user security context of the NT account running the MSSQLServer service. If a user types the commandįrom a T-SQL session, the system returns the output "dir c:\" as the query's result set. For example, xp_cmdshell is an extended stored procedure that lets SQL Server users issue a Transact SQL (T-SQL) command as if they were typing in a command prompt window. This default setting can lead to security problems. By default, the setup program installs MSSQLServer to run as a LocalSystem account, giving users powerful rights and privileges. You have two account choices: You can run a service as LocalSystem, which is an administrator account with powerful rights and privileges, or you can run a service as normal, which is an account with the rights of an ordinary system user. This configuration lets users assign permissions and rights to a service by assigning those permissions and rights to the underlying NT account.

Like any NT service, MSSQLServer must run within the security context of an NT account.

SQL Server is a Windows NT service called MSSQLServer. Many people are familiar with these performance problems, but not everyone realizes the potential security risks associated with SQL Server installed on a domain controller. Performance degradation is not noticeably great, unless you don't have enough domain controllers to handle the network load. Performance is affected because the domain controller consumes memory, CPU, and other resources that a member server would delegate to SQL Server. To avoid performance and security problems, we encourage you to install SQL Server on a member server in a domain, rather than a Primary Domain Controller (PDC) or Backup Domain Controller (BDC). As a general strategy when you're running MTS, use the same connection parameters (i.e., username and password) to help provide maximum reuse of connections.ĭoes installing SQL Server on a domain controller affect security and performance? The system responded with the error message Unable to read login packets. We duplicated anomalous behavior by using ActiveX Data Object (ADO) to connect to SQL Server 6.5 over Named Pipes while we were running Microsoft Transaction Server (MTS). When you use ODBC connection pooling, Named Pipe NetLib connections are slower and might cause erratic behavior. Q: Do some NetLibs behave differently when you use Open Database Connectivity (ODBC) connection pooling?
