Hi I am using network analyst for the first time (as a student). I am trying to build a network dataset. After going through and completing the wizard via ArcCatalog, it says 'the network dataset has been created. Would you like to build it now?', so I click yes, then I get the error 'Build Network Dataset failed. File read/write error occurred. System junction source does not exist.' If i right click on the created ND and choose 'Build' after this I get the error 'file read/write error occurred'. I have sent the original data to my lecturer who has managed to create and build the ND OK, following the steps I have used, so it is some kind of issue with my computer. I have a new computer running Windows with 8gb RAM, and running ArcGIS 9.3 and as far as I know I have full permissions etc. Does anybody have any suggestions?
Update: I found an ESRI page which mentioned a similar issue when running this on a computer with over 3gb RAM. The solution involved editing the registry to minimise the amount of RAM used for the process. So I followed this. Still got the same error when creating the ND.
Update: I found and installed SP1 and everything seems to be working OK now. Phew.
