MaxDB Error code 3700 "hostfile_error" ERRORTEXT="Could not open stream"

Hi all,

First let me start that the SDN is the greatest source of information for SAP and i would like to make a contribution one day but at the moment i have a problem which i'll be greatful if you guys could assist me in solving: here is the problem

Im running Maxdb 7.7.0.16 with windows x64 server 2003, im trying to backup over the network to a share drive both the machines are joined to the domain firewalls are down im using the same user to try the backup the error that im getting is this :

Thread  0x105 Task     86  2010-11-16 08:47:48     Backup         1:  Backupmedium #1 (
10.1.103.119\h\BHS\BHS_WEEKLY) Could not open stream

2010-11-16 08:47:48     KernelComm     6:  Backup error occured, Error code 3700 "hostfile_error"

as soon as i try to do the backup to the local hard rivers it works fine but as soon as i try run it over the network i get the above error see below for the knlmsg.log file

the following things Iu2019ve tried after searching SDN

Change Parameter CacheMemorySize to higher and lower made no differences

Change Parameter MaxBackupMedia to higher and no change

I've also tried copying a backed up template off the local drive across to the network share and i can read the label but as soon as i try to do a backup the error occurs
