клиент - ос = Microsoft Windows Server 2003 Enterprise Edition Service Pack 1
1-ый сервер - ос = руссифицированный Microsoft Windows 2000 server с sp4
и бд = Microsoft SQL Server Enterprise Edition Version 9.00.1399.06
2-й ос =
и бд = Microsoft SQL Server Enterprise Edition Version 8.00.760

в рамках TransactionScope
пытаюсь выполнить запросы на select к этим двум бд
1-ый на 1-ый сервер
2-ой на 2-ой сервер
на втором запросе возникает ошибка
как ее ликвидировать ?

а как узнать прилинкованы они или нет
и как их прилинковать, если нет

а если нужны два разных соеденинения в рамках одной транзакции, то как быть

удалось выполнить распределенный запрос с 1-ого сервера на 2-ой
а вот точно такой же запрос с 3-го на 2-ой не удалось
в чем может быть проблема
