Error at input of Cyrillic characters HTTP 500 (12217)
At input of Cyrillic characters in the field of search of the client

there is an error

The error occurs at editing of many fields, not only by search.
The problem appears only at logon through the external address (www.myadress.ru).
At an input through a local area network (licalhost:8080) - all is normal.
Whether can the problem reason be proxy server usage (ISA 2006) ?
