What steps will reproduce the problem?
Try to insert row in some table using transaction with pdo_sqlsrv driver (version 2.0)

What is the expected output? What do you see instead?
Inserted must be successful, but there are specific errors about MARS (feature of MSSQL) with point to "beginTransaction" (CMssqlPdoAdapter.php, line 45 - $this->exec('BEGIN TRANSACTION');)

What version of the product are you using? On what operating system?
Yii 1.1.8, sqlsrv 2.0, MSSQL 2008

Please provide any additional information below.
New driver for MSSQL - sqlsrv - already has features for transaction - begin, commit and revoke, like other pdo drivers. So, for sqlsrv don't need use old version of using transaction ($this->exec('BEGIN TRANSACTION');), moreover, old version raises errors. Sqlsrv must use common PDO class.

Solving - change line 401 at file CDbConnection.php:
if($driver==='mssql' || $driver==='dblib' || $driver==='sqlsrv')
if($driver==='mssql' || $driver==='dblib')
Now sqlsrv uses PDO driver instead of CMssqlPdoAdapter and all good!

Some problem - pdo_sqlsrv has wrong implementation of lastInsertId(): when parameter $sequence is null, method work wrong - return nothing, and in this case we must call method without parameter for proper value of last insert id.

Because of this problem we can't just use PDO class for sqlsrv, we must implement method lastInsertId() (and nothing else!) in some PDO adapter class like CMSsqlPdoAdapter or see what driver we use when call methods of CMSsqlPdoAdapter.

Differents of CMssqlPdoAdapter and required CSqlsrvPdoAdapter:
CMssqlPdoAdapter extends 4 methods - lastInsertId, beginTransaction, commit and rollBack.
CSqlsrvPdoAdapter must extends only 1 method (at now :) ) - lastInsertId:
public function lastInsertId ($sequence=NULL)
$value = $sequence ? parent::lastInsertId($sequence) : parent::lastInsertId();
$value=preg_replace('/[,.]0+$/', '', $value); // issue 2312
return strtr($value,array(','=>'','.'=>''));

I am using php_pdo_sqlsrv_53_nts_vc9.dll version 2.0.1802.200 running against MSSQL 2005. The PDO driver's implementation of lastInsertId is working for me.

None of the Yii 1.1.8 CMssqlPdoAdapter override methods are working for me. So using the PDO driver instead of CMssqlPdoAdapter fixed everything for me.

Maybe this issue exists only on MSSQL 2008 ... I'll try to do test set.

Same thing:

SQLSTATE[42000]: [Microsoft][SQL Server Native Client 10.0][SQL Server]A transaction that was started in a MARS batch is still active at the end of the batch. The transaction is rolled back. (C:\WWW\framework\db\schema\mssql\CMssqlPdoAdapter.php:44)

#0 C:\WWW\manager\framework\framework\db\schema\mssql\CMssqlPdoAdapter.php(44): PDO->exec('BEGIN TRANSACTI...')

@iGrog temporary solution is to disable MARS. Add ;MultipleActiveResultSets=false to your DSN, so it should look like:
