When I attempt to login to ArcGIS online from ArcMap 10.0 (running on Citrix) I get an Unable to connect to ArcGIS online error and the connection test results show:
Proxy Server Test - Failed
Reason Unknown.
Download Speed Test - Failed
Test site unreachable.
Network Latency Test - Passed
Network latency 0 ms. Rating Excellent
Network Route Test - Passed
Network route solved with 1 nodes.
IT folks tell me we don't have a Proxy Server - Any ideas?
