We moved (3000 users, 50 network printers, 6 MS Windows 2003 File and print servers) from one physical location to another. Apparently, the network folks managed to replicate the old network at the new location: same network configs, same subnet, same network speed, etc. Alas, at the new location, the 3000 users have the following issue:
when they click on File - Print (from any application, for example MS Word, Adobe pdfs, etc), it takes 10 to 15 more seconds (compared to what it was at the old location), then the printer window selection appears. From there, they select whatever printer we have and they click on print. As soon as they click on Print, it takes in between 35 seconds to 5 minutes before MS Windows confrms that the job was sent to the printer (during that time, MS Windows hangs with the hour glass)...instead of 2 to 3 seconds (for the exact same type of documents, exact same size of documents too). At first, we thought we found the culprit: the network printers were set to auto/auto instead of 100mb full duplex at the new location. We changed the setting back to 100mb full duplex on the printers and got the network folks to set the switch ports of the network printers lan drops to 100mb full (which was the setup at the old location). But that did change nothing. The above mentioned issue is still there. The other thing that we noticed is that towards the end of the day, when most users have left, it gets better. When all users are working, the issue worsens. But at the old location, even during peak hours (with all users working), we did not experience with that generalized slowness. At this point, the network team is out of solutions. What is your take about this? Could that be a network congestion issue with our subnets (they are all on the same subnets they used to be at the old location. The network team says NO, because we had the set up at the old location. However, when I take one of those 3000 computers and set them on a subnet that has nothing to do with the subnets that have moved...the problem disappears. The network team continues to ignore that possibility but I just can't find the right technical argument to explain that it could perhaps be a subnet issue based on that computer that works fine on a subnet that has nothing to do with the subnets that have moved).
OS of the 3000 desktop computers: Windows 7 (they are all set to auto/auto in the computer network configs, same on switch ports)
All network printers are Ricoh Aficio mp 7001, they are all hardcoded at 100mb full duplex on the printer as well as on the network printer lan drop's switch port (we tried auto/auto but it continued to be extremely slow). This is somehow related just to the printing as people can browse their network folder as well as the web without any problem.
