Your contemplating running IPv6, your using Microsoft products, and you want to know what will work, and what wont?
Below is a table from testing that IFM has done using SBS 2003 with SP1 and XP SP2.
| Service | Works? | Comments |
| OWA | Yes | No issues with Outlook Web Access. |
| File and Printer Sharing | Yes | No issues. |
| FRS | Yes | No issues with File Replication Service (or domain controllers or Active Directory) in general. |
| Sharepoint | Yes | No issues (but not heavily tested). |
| IAS | Yes | No issues with Internet Authentication Service (but not heavily tested). |
| IIS | Barely | If by "works" you mean can it serve up WWW pages, then yes, it works. However, most of the security restrictions (such as by IP address) don't work, and worse still, even if you have applied restrictions on an IPv4 site IPv6 connected people will still be able to access the site without restrictions. Big security holes. |
| RPC over HTTPS proxy | No | The RPC proxy itself works, but it fails when it tries to pass the call off to the actual RPC service. |
| Microsoft fax Server | No | Clients are completely unable to submit faxes via the fax printer driver. |
| DNS Server | Mostly | You can make queries to it and get results. However if you host a domain with IPv6 AAAA NS records, then the server fails to return the AAAA glue records (only returns A glue records). Also, it is rather painful trying to make the DNS server actually accept IPv6 AAAA NS records. |
| Exchange 2003 | Yes | No issues. |
| SQL Server 2000 | Yes | No issues (but not heavily tested). |
| ISA | Don't know | What, you actually use this piece of software? Throw it away, and buy yourself a proper firewall! |
