I am long time SQL guy but relatively new to NAV. We currently have one server setup to do everything that works fine which was for deployment. But now it is in production and I am still working on getting the production environment to work. I am trying to setup the three tiers with the client on terminal server (done and working great), the app tier on a pair of load balanced servers, (probelms) and the database tier on a SQL 2008 cluster (problems).
Supposedly this is supported but I still have not completely got it set.
1. Problem the NAV Database components won't install except on a local instance, it cannot find the cluster instance, however I copied the DLL and ran the stored procedures and I believe it is working excpet I cannot upgrade the database to SQ1 successfully.
2. If I run the RTC clinet on the application servers I can open NAV and connect to the database. If I use a RTC client on another machine and connect through the App servers either as the load balanced name or the individual name it fails and says Login Failed when connecting to SQL Server <DB0SQL>. I can connect from the classic client to the clustered instance and access the database.
So I believe my issue is with the app server. I am trying to use domain accounts and have gotten to this point but I have not found much documentation and I am hoping someone out there has gotten this to work and has some advice or someone might have a suggestion. I have setup SPNs and delegation but the app server does not seam to be able to pass credentials through it so it may be a delegation issue.
Thanks for any help.
