Is there any simple way to run same sql script on multiple remote sql server databases at once?

Question

i am using sql server 2005. our company has many branches. each branch is located in different country. so when i update database in any country over the VPN connection then i need to update db in another country one by one over the vpn connection. it
is very tire some job....so i was think that there could be any easy trick to update multiple db in different country easily. so am developing a store procedure which will connect each DB in different database one after one over the vpn and read script from
sql file and execute the script in remote db over vpn. so please have look at my script and tell me how to do it. please do not advise me to use any 3rd party.
here is a table structure where i will put all my remote db details.
CREATE TABLE [dbo].[DBDetails]
[ServerName] [varchar](max)     NULL,
[DBName] [varchar](max)         NULL,
[UserID] [varchar](max)         NULL,
[Password] [varchar](max)       NULL,
[CountryCode] [varchar](2)      NULL
SET NOCOUNT ON
DECLARE DB CURSOR FOR SELECT ServerName,DBName,UserID,Password,CountryCode FROM    DBDetails
OPEN DB
DECLARE @ServerName     varchar(MAX)
DECLARE @DBName         varchar(MAX)
DECLARE @UserID         varchar(MAX)
DECLARE @Password       varchar(MAX)
DECLARE @CountryCode    varchar(2)
FETCH NEXT FROM DB INTO @ServerName,@DBName,@UserID,@Password,@CountryCode
WHILE @@FETCH_STATUS = 0
BEGIN
-- here i need some help for opening db connection and read sql file and execute  the statement
-- Please help here
FETCH NEXT FROM DB INTO @ServerName,@DBName,@UserID,@Password,@CountryCode
 END
 CLOSE DB
 DEALLOCATE DB
thanks

One way: set them as jobs and assign the same schedule or start them from a stored procedure:

Note: when you start a job from a stored procedure, control proceeds to the next statement, there is no wait for the job to finish.
