Copy to Sysvol Very Slow

When I copy to the sysvol, a file takes ~3minutes to copy, where as if i copy to a DC in the site via \\server\sysvol\domain\, it takes ~10 seconds.  I don't see replicaiton errors in the logs.  I have looked over assignment of subnets in sites and services and it looks to be good.  This is a new occurance.  Until about a month ago, copying to the sysvol was just fine.

Domain & Forest are 2003 function level

8 sites, the site in question has 3 DCs.

from what I can tell, replication is very healthy.  Replmon and ultrasound concur and files place in the sysvol at the site in question replicate quickly.  It seems that the server in question is going off site when it copies to the sysvol.  So, how do I one figure out what site it thinks its in and two correct the server?

Have you created subnets in AD Sites and Services and assigned them to the correct site?

So I can assume the IP to the spesific server, has a subnet defined in AD S&S?

Do all clients have this delay copying to SYSVOL?

No, clients okay, in fact doing some testing I find that
1.  it's only one server that exhibits this behavior that I have found so far.
2.  I have found that DC that the trouble server considers authoritative for the sysvol.  The problem server and it's preferred DC are in different sites.  
3.  The logon server of the trouble server is in the same site with the trouble server, but it isn't looking to it for sysvol queries.

Let’s say site 1is the main site and site two is the distant site

Server A is ‘the trouble server’.  Server B is the DC listed by Server A is it’s logon server when I log in.  Server A and B are in site 1.  Server C is the DC in site 2.  Server B is looking to server C for sysvol queries.  Very odd.  The subnets folder in AD S&S is populated with my subnets and they are assigned to sites.  Sites list their correct DCs.

When "Server A" authenticate towards a DC in its site, it does not mean it will use the SYSVOL that the authenticating DC holds.

The authenticating DC (GC) will send "Server A" a list of SYSVOL servers across the domain.

1. All site-local SYSVOL servers
2. A random list of all SYSVOLs (not based on site link costs)

"Server A" should pick a SYSVOL from #1. If all those are unavalible, it will pick one from #2.

Why "Server A" picks one from #2 in your case, can be caused by lots of things. Take a look at possible causes that the MS Storage team made.

(they talk about DFS, but SYSVOL = DFS namespace)
