Network error while backup

We get an error when we are trying to run a backup of the SQL db here, we just got a new ISP to this company and al the routers and the like has been reconfigured (if that might be the problem). Would apreciate a speedy help with this one.
Here is the error message we get

un OnStart: DTSStep_DTSExecuteSQLTask_2 DTSRun OnError: DTSStep_DTSExecuteSQLTask_2, Error = -2147467259 (80004005) Error string: [DBNETLIB][ConnectionRead (recv()).]General network error.

Process Exit Code 1. The step failed.Why you're using DTS to take backup, the best option would be to perform a local backup of database on the server and use FTP or other file transfer options to transfer the file.

The potential causes of general network would be:
- any issues with network routers, hubs involved.
- check event viewer for any network issues
- SQL Server is not listening on the protocol or port that you are using to connect. The Server Network Utility on the server determines which protocols SQL Server will use and on which TCP/IP ports SQL Server will listen.
- The Client Network Utility, an MDAC data source name (DSN), or your connection string determines which protocol and port your client uses when it connects.|||Thansk for the help i will look in to this :)|||What are the privileges held for MSSQLSErver & SQLAgent service account?|||Admin and connecting using Remote Desktop thru a TS server|||How about privileges on the desktop/remote server for these accounts?|||full acces for the admin
they got all the neccesary priveliges
the error ocuurd after the change of ISP it has worked fine before that so we are thinking it might be routing or something like that but we are not sure.|||Thats better, then dig out from other end/|||hehe :) we have looked in to that but we cant find anything wrong with it at the moment :) thats why i posted it here to get some feedback what it might be so thanks for the help m8|||Any firewall involved or any new tools installed recently at ISP and your end?

In order to determine whether this "general network error" is a
Net-Library, a Network Protocol, or a name resolution problem, there are a few troubleshooting steps that should be tried.

Take help from this KBA http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q169/7/90.asp&NoWebContent=1 to troubleshoot if TCP/IP is defaulted.

Best option to talk to ISP techies for useful information.|||yea we will do that i do also think they have done some configuring here that our network and SQL server didnt like.
If we dont solve this our self they will have e great weekend fixing this shit here :)

thanks again|||Only this backup job fails or a simple DTS also fails which involves file copy.

ALso try to OS level to copy the files.|||Will do that... looks like it will be work for me this weekend to :(
But i dont think there is anything wrong with the filecopying i think it is when it tries to resolve all the backup locations in the network here but as i said i will try everthing that might help :)sql
