Managing Distributed Transactions with ADO.NET 2.0 using TransactionScope gives error message

Question

Hi, I am working on vs2005 with sql server 2000. I have used TransactionScope class. Example Reference: http://www.c-sharpcorner.com/UploadFile/mosessaur/TransactionScope04142006103850AM/TransactionScope.aspx The code is given below. using System.Transactions; protected void Page_Load(object sender, EventArgs e) { System.Transactions.TransactionOptions transOption = new System.Transactions.TransactionOptions(); transOption.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted; transOption.Timeout = new TimeSpan(0, 2, 0); using (System.Transactions.TransactionScope tranScope = new System.Transactions.TransactionScope(TransactionScopeOption.Required,transOption)) { using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["nwConnString"].ConnectionString)) { int i; con.Open(); SqlCommand cmd = new SqlCommand("update products set unitsinstock=100 where productid=1", con); i = cmd.ExecuteNonQuery(); if (i > 0) { using (SqlConnection conInner = new SqlConnection(ConfigurationManager.ConnectionStrings["pubsConnString"].ConnectionString)) { conInner.Open(); SqlCommand cmdInner = new SqlCommand("update Salary set sal=5000 where eno=1", conInner); i = cmdInner.ExecuteNonQuery(); if (i > 0) { tranScope.Complete(); } } } } } } It gives error like "The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025)" The database I have used is northwind database and pubs database which is by default in sql server 2000. So, Kindly let me know how to proceed further. Thanks in advance, Arun.
